### Tips to reduce Plastic use - You must try

As we already know we are on the mission of reducing plastic waste. so, here are the different ways to live with less waste.

First, it’s important to know the four R’s
R = refuse what you don’t need
R= reduce what you do need
R= reuse by using what you have
R= recycle what you can

Today, we’ll start with refuse. Refusing is the first rule of living a zero-waste lifestyle. Think before accepting anything into your home. Turn down flyers and junk mail, freebies, party favors any other junk that will most likely go into the trash.
Each year people throw away 100 millions plastic grocery bags which take about 1000 years to breakdown.

1. Instead of taking plastic bags and creating more demand for them, use reusable cloth bags or even no bag, when possible. I used to think it was mandatory to use these plastic bags for your fruits and vegetables, but I recently discovered you can just use your own bag or even no bag, which is even better because why bring home extra plastic? You could also bring own jars to grocery stores to avoid bringing home any unnecessary plastic containers. I love when grocery stores sell the thing in bulk so that it’s really easy to do some zero waste shopping. You can either weigh your jars at the front beforehand or bring an extra of the same jar so you can weight it at checkout.

2. Instead of using a one-time disposable plastic straw, you can either refuse the straw completely or use an acrylic or steel straw instead. I personally like to drink my smoothies with a straw, so I have this acrylic straw for that specific purpose.

3. Instead of using this plastic cling wrap in your kitchen to preserve your food and leftovers, switch to using this sustainable and reusable food wrap. These are all-natural, organic and compostable. I believe they're made out of beeswax and they actually do a really good job at keeping your food fresh, even better than plastic in my opinion.

4. Instead of buying disposable plastic water bottles, opt for a reusable water bottle that you can fill up again and again. Glass and steel are probably best for your water bottle.

5. Instead of using disposable utensils. Do your best to avoid using disposable utensils. Instead you can bring silverware from the use or use portable made out of stainless steel or bamboo or leaf cutlery.

6. Over 4.7 billion plastic toothbrushes that will never biodegrade dumped in landfills and ocean each year. So you can make a huge impact just by switching out your plastic toothbrush for a sustainable bamboo toothbrush. Think of all plastic toothbrush that you use in one lifetime and imagine avoiding that waste completely, just by switching to something that’s biodegradable and compostable.

7. Lastly, reduce the amount of paper you bring into your home by switching to paperless whenever possible. Do this with your mail, your bills, your notes, and your books. U personally love reading ebooks, but I know some people love traditional books, so just do whatever works for you.

I hope you liked tips on how to balanced life with less waste. I just want to remind you though: just take it one step at a time.. don’t be so hard on yourself. It’s a journey. All that matters is that you're becoming aware, more conscious of the environment and you’re doing your best, okay?

Everyone is at a different point in their journey and  No one is perfect. I am not totally zero waste yet. But I think the first step is awareness. And then after that, you will start to reduce your waste little by little. So let’s create a non-judgemental, welcoming space where we can just open up the discussion around reducing uor waste. And lets not judge others who aren’t aware of this lifestyle.

The best thing you can do is just be a living example of what you want to see in the world. And let your action speak louder than your words.

### NEVER EVER LOOSE HOPE

If you want to achieve success in your life, you need to work hard. You need to live with determination. You need to have patience and even after following all of these things, we will still have to face challenges in our life.

We Fail,
We Fall,
And become hopeless.

And everyone knows, Hopelessness is the biggest enemy of success. If you become hopeless, you will loose everything very easily.

Whenever you feel hopeless, just remember one thing ‘when you tried, again and again, you will definitely achieve the success.’

For example- When a giraffe mother gives birth to a baby, the giraffe mother is very tall and the baby giraffe falls on the ground with a force.

And as it tries to understand where it has fallen. Mother giraffe stand over it and kicks it really very hard. So, the baby giraffe falls at a distance and tries to understand what was happened with him and gather all its senses. Again the mother comes and stands over it and again gives it another hard kick. After that the baby giraffe understands, if I didn’t act now, I will keep getting kicks.’ Than he starts trying to get up with on its wobbly legs. But her mother kicks again.

Finally, the baby giraffe understand, “If I don’t stand and run, I will be kicked again and again. So, the baby giraffe starts running and at that moment, the mother comes and starts kissing the baby because the baby giraffe is ready to take care of itself. Because mother can’t stay with the baby all the time.

So if it goes away, who will protect the baby?

That’s why mother giraffe kick to the baby so that it learns how to stand, she kick again so that the baby remember how to stand. And the last kick is just to remind that not to stand up but start running.
In life, challenges will come. Sometimes we will fall; we will fail, but don’t lose your hope.

Whenever challenges come your way, no matter how many of time you will fail or fall, learn to get up and start running.

If you learn to get up, stand up and start running. Then you will reach the highest peak of success.👍💗
