I am not afraid to learn new skills and try new techniques. I sometimes gump things up, and when I do, I kick myself, but I don't do the same mistake again.
There are some guns I own that I bought only because I wanted to tinker with them, or simply open them up and see how they function.
Amen to all that! And when one turns out good, you end up with something that is much more valuable (to you), than one you might have bought new. Not to mention the knowledge and skill gained in the process.
