Being Firm

Think that by being firm on what you want to do, you can achieve the things you want. I'm trying to change something in my life which I have been doing for many years, but when the time comes to change, I started to ponder and become indecisive. Now it have become a draggy affair which mentally drained me. How I wish I was firm and execute the things I want to do in the first place. Is it because I think too much? Or because I have been doing for the past 11 years that I need time to adjust it. this really affect my thinking and I just want to get the things done with and move on. Hope things can go my way and everything can be settle fast and harmony.
