wasted time

so I was thinking last night, and I probably wont remember this quite the way it came through my head last night, but I realize I've pretty much wasted the last 25 or so years of my life by not being satisfied with who I am.

When I was in my early twenties, I was never happy with my weight, my hair, my looks. And now that I'm 41, I'd really give anything to have even the waist I had when I was 30, and certainly the face I had then. And I felt every day was a bad hair day.

So I wonder, am I going to waste my forties obsessing about the weight I am now and the lines on my face that I have now and be looking back in my fifties wishing I could look like I was forty again?

when am I going to just be happy for where I am and what I am when I am right there?
