Does anyone else do this to themselves? How do I keep from beating myself up all the time?

I've actually been working on it for the past few years when it comes to self-image. Looks, diet, athletic performance...I've improved greatly in this area and I'm not nearly as hard on myself as I used to be which is a big relief. I think part if it is actually aging and lifestyle change where I put a lot less importance on appearances anyway.

But man, when it comes to accomplishing things I'd set out to do, I'm relentless. The latest is our '72 VW Super Beetle. Today she was picked up by a towing company because we donated her to the Oregon Humane Society. They told me that she'd fetch a great price at auction, so they were very pleased. I should be as well but instead, I'm feeling incredibly guilty for 'giving up'. The poor thing sat in our garage awaiting restoration for 2 years before I finally had to admit that I was never going to get to it. And now I feel guilty for admitting defeat.

We are also currently working on putting our house on the market and moving into town. I alternate between insane guilt for 'giving up' on the sustainable farming thing and excitement at our eventual ability to get a real handle on our lives for the first time in 4 years. I shouldn't feel guilty about this, but I do. I'd set out to do something and I am beating the crap out of myself for not following through with it anymore.

How do I stop this?
