Your past shouldn't define you nor your present conditions. You got lots to achieve in the future, don't allow what you are going through now to weigh you down, don't, I say don't.
You have what it takes to become the best you in life. Don't feel inferior, because you are not inferior, you are superior. Always remember, "Your starting point isn't greater than your end-point."
You failed? Don't feel sad, every wealthy and worthy men once failed. Don't just stop striving, there is hope as long as you still lives.
