Today I decided that I really can set goals and stick to them. Want to know how I know?
When I was a baby, I was so helpless I couldn't even walk. That fact notwithstanding, I learned to crawl, and from there learned to stand, and finally learned to walk. Everyone was so proud of me, and you know what? I haven't given up walking since.
See? Setting and accomplishing life-long goals just comes naturally to me. I can do it!
