Responsibility... What's that?

Yes that's an MxPx song, but really I feel like that's what's going on right now. My life is good but I know for it to continue this way I need to have some more responsibility in my life. For too long I've floated on by not realizing I've helped others reach their goals and not my own. Although it has been so rewarding to do so I feel its time for me to 'do me' and see where it leads me.
Why has it taken me so long to want this? Its the F word. FEAR... The fear of criticism/judgment, the fear of failure, the fear of letting others down and of course the fear of responsibility. Ugghh...
But I know its time. I'm in a great place in my life and I'm ready to move this life of mine along. To take that leap of responsibility. To make my dreams become a reality and smash my goals.
