life is good

— Bro, I don't feel confident at all... I don't know what I care..

What are you whining about, quickly picked up your snot from the floor and listen to me 

Everyone has the right to become what they dreamed of, does whining bring you closer to that?

Of course not 
The way out: every time you feel sad, just try to get through this stage calmly, distract yourself, but don't get off the main goal.

Bro, I want you to understand that you just need to go to the goal, perseverance will help you.
