Well, there is a study published by overflow folks, it said 80 % of the hackers are unhappy and want change guess why because this kind of lifestyle where code code code is messy and demands a lot of energy most hackers I have come across are not physically fit and find it challenging and get into stress.

Don;t fall into stress

Take breaks,
Amuse yourself with other expression.
Code but don't re-invent everything
Make apps , libs, framework, etc and open for mistakes while making them
Don't get into ship right now moment and lose your sleep over that.

Good day
