Aim High, stick to it. Know your limits, that's right there isn't one. When you feel exhausted, keep working till you don't feel it.
I might seem like a really arrogant person but know that I am not. I wear a mask most of the times, not to hide myself from others but to hide myself from me which I relentlessly fail....
Don't try to run from nightmares
Don't try to linger in fantasies
