Life is a Disappoinment or Am I the disappointment?

Review my life. Nothing achieved. Where's the success?? Nada.... So is it life a disappointment or am I the disappointment?????  Should I just sit here in the corner and stare and ponder all the time about it?? or I just go out of this corner and just have fun. And forget about all the ideals. Never look back. And just continue on with my life. But there must be something that will become the highlight of my life. Because, everyone's and anyone's life is a story, must have the peak time and the down time. True?
