Do you feel like you've done everything to become a good person yet your life treats you like youre worthless?

I want to know what others think of themselves. but I personally believe that life is hard no matter how capable of a person you are. Life is hard enough for even the strongest, the most talented, the most inspiring, the most intelligent, the most gifted. I personally consider myself to be very fortunate but during the day im confronted with things that just put me down making me feel like im far behind. Looking at it as a whole, I perceive myself lacking in very little yet dont understand why life generally makes me feel like a loser. I often wonder how others fare. Please give a specific example of how you feel like life demanded something out of you after you already gave it your best!
