The world doesn't owe me anything

 One of the best things Christianity has done for my mentality is it makes me less entitled, while also giving me self-worth.

And I recognize the way I think about this is going to be highly controversial, as it is counter to conventional rhetoric in pop psychology. 

But I am not *deserving* of better things. Me doing my best to be a decent human being does not make me "deserving" of any of life's luxuries.

That's just not the way the world works; it's not tit for tat. It doesn't owe me anything. ("The swift do not always win the race...")

All the good I get is God's undeserved kindness, evidence of the fact that even though I may not be deserving, I am unarguably of great value.

Even though I am imperfect, even though the world doesn't owe me anything, God has deemed me priceless.

He paid the highest price for me, for my unique self. 

The world doesn't owe me anything, so I do not become indignant when life doesn't go my way. But I am extremely, universally, intrinsically valuable; nothing and nobody else can replace me, and God gives and will continue me good gifts and perfect presents because even though he doesn't owe me anything, he values me.

And I am albeit slowly, learning to accept his good gifts gratefully.
