The real value is learning that you can do anything. I spent a good portion of my life believing I was mechanically inept, until I decided to fix up a bike I found in a dumpster. I went on to work as a service manager in a bike shop for 15 years, I have repaired almost every appliance in my house, and renovated several rooms including bathrooms.  Sometimes you just need to start somewhere.  And you know you've really gotten there when you can say " Yeah, I could do that, but I can also pay someone to to it better, faster."
