you should learn to let go of your stresses and never sleep with you can do something about it just do it in the other case, just leave it and work towards its goals or else it just kills your productivity.

Never feel disappointed in life and stop trying when life offers you struggles but keep on fighting until you see success.

you should identify your priorities in life and develop a good strategy to work towards fulfilling them rather than wasting your time and effort on unnecessary aspects of life.

Keep trying always and never give up despite multiple failures.

The skills abilities are only useful if you are in the right place at the right time. otherwise, they go to waste. 

If you waste your time, then you waste your life.
