release pressure, don't take too seriously.

 Sometimes it can feel like you are carrying a piano on your back. Pressure can really weigh you down.

Too much pressure can make a lot of us angry, feed up or sad. Or simply, over time, knock you out cold with a burnout.

Now I don't how your mind works but personally I perform better without a lot of pressure. It's easier to focus on your task and not second-guess or hold yourself back when you feel light and relaxed.

Like most problems in life this one is mostly in our minds. You can actually remove some of that pressure before it gets the best of you.

you can look some tips here:

Don't listen too much to others.

If you use too much time and energy to focus on these three things you may be heading down a pretty harmful road. And the thing is, most people aren't thinking about you, what you do and your problems as much as you may fear anyway.

It can make you end up filled up with negative feelings and that won't help anyone. And, as I said above, you don't really know what people think about you anyway. Your worries about what people may think about you are probably mostly in your head.

just think that it's just their opinion.

Forget about perfectionism.

Perfectionism is pretty pointless. It's just you putting unnecessary pressure on yourself and thereby reducing your ability to do excellent work.

Take a look at the next point to find a better replacement for perfectionism.

Focus on the process, not on the outcome.

Detaching from the possible outcomes and just keeping your focus on the work you are doing makes it easier to both live and live up to your potential by reducing many of your inner, mental obstacles such as performance anxiety and other worries.

Feel free to make more mistakes

Make more mistakes to be mature, don't shy to make more mistakes or care about people who always talk about your failures, mistakes. once you make alot mistakes, you can prove them wrong. 

Make more mistakes at first, make more achievements at last.

Cut down on busywork and unimportant stuff.

Feeling like you just have too much to do and too little time for the most important things?

Then you probably need to do some decluttering in your life. Eliminate some of the less important stuff.

To prioritize and find what's really important to spend most of your time on, both at work/in school and life in general you can use the 80/20 rule.
