What I'm hearing are tasks working towards several straightforward goals. The big, audacious goal you are inspired by isn't clear. What do you really want to work towards? You KNOW you can work on your house and your body. What aren't you sure you can do, but would love to prove you can?

I guess what I'm saying is, set a concrete goal which motivates you to do these things in your life, but take them 2 steps beyond what you're thinking of now. Learn and explore what you can do. If you find you're failing, you'll also find you're learning your capabilities and are expanding them too.

Don't be afraid to see if you can fly.
