Need some inspiration to get past frustration

Sometimes I feel like I'm falling behind. That I should have accomplished so much more than I actually have. I will hear a song, read a book, or watch a movie that involves someone my age and think "What did they do to get so far in life when I can't get past this road block?" I may have brought this on myself, but at the same time I don't know how or how to get past it. I want so much out of life that nothing seems possible.
