I didn't know my dad for a long time. My dad was on drugs and my dad was at the VA Hospital, my dad was off in his own world selling drugs or using them or there would be crack heads in the house or whatever it would be.
Don't be afraid to give your best to what seemingly are small jobs. Every time you conquer one it makes you that much stronger. If you do the little jobs well, the big ones will tend to take care of themselves.
