If you don't have the maturity to just accept the world as it goes,
You will forever be fighting with yourself and others over the tiniest events.
Do not stop at a single level looking for imperfections. Also don't just skip your levels because you had 5 bad days, take your time and learn to make the best of everything.
If you can't change your trouble into a solution, stoping crying over the inconvenience and starting focusing on the merits of it.
Everyone goes through hardships,
with time you learn to embrace them and turn them into your strengths.
There is no destined happiness, it goes with a flow, you have it and then you don't.
Forgive your past,
Accept your present,
And work on your future.
