Hey hustlers, I hope you're doing great.

Today is Sunday, which means resting the whole day, right??
โœ… Yes ๐Ÿ˜Ž
โŒ Nope 
 
Remember who we are. We are hustlers who don't give excuses, and our aim is much bigger. For that, we break all tasks into smaller tasks and try to achieve them all at once.

 
Don;t forget on these important part of this challenge
1. Taking enough amount sleep of 6โ€“8 hours daily

2. Eating only healthy and home-made food and trying to avoid junk food as much as possible to eliminate sugary and packaged food

3. Daily 30 minutes of exercise. Here, you don't need to join any gym; you can do just walking and some yoga to make us stronger. 

4. Drinking 3โ€“4 litres of water

5. At least 2 minutes of deep breathing will make us calm and focus on only positive things. This will eliminate all your anxiety and negativity.

6. Try to give a minimum 1 hour for learning new skills, which can be helpful for getting a better job or making money.

So today's task is to understand more advanced concepts in math and statistics. Here are more resources for your learning.
