Setbacks are a part of the game.
Expecting a path to anything worthy without setbacks is an unrealistic expectation that will leave you frustrated, angry, and bitter.
The only real difference between you and all those people living the life you want to live is that those people fought through the setbacks...
...and you haven't.
You quit.
You changed the plan.
They kept going.
That's essentially it.
So stop pouting...
Wipe your tears...
...and get in the fucking game.
