What More Can I Do?

I am very frustrated right now. I am frustrated with my job. I am frustrated with my financial situation. I am frustrated with my health and wellness. I am frustrated with some of my relationships. But mostly I am frustrated with myself because I have a tendency to psych myself out of achieving the things I want. Too many times I sabotage myself by thinking "I'm just not good enough." I know that I have a big personality and come off as cock-sure and cavalier, but I really do have my own issues that cause me to self destruct. Something has got to give soon. I just need one good thing to happen in my life. I don't think that is too much to ask.
