An honest prayer

I've given up the fact that I'll ever be blessed with an easy path in life.  If I get 2 steps forward, the very next week, I'm knocked 22 steps back.  It's unbelievably frustrating.  So today, I decided to stop whining and pray this prayer - "Dear Lord, if my life isn't going to be easy, then please give me the strength to handle it. That means please help me to become healthy and strong.  Please help with perseverance and consistency.  Help me not to fall back into my old ways but stick to my new ones."  I feel like this is a fairly humble prayer.  I'm not asking for money or luck, just strength to change my habits that are giving me bad luck.
