Agree! Ten years ago I was the kind of guy who, literally, didn't know how to swing a hammer. I'm still not very good with a hammer... but I can now do just about anything that needs to be done on a bicycle. I started with simple projects like fixing a flat tire, adjusting the derailleurs and replacing handlebar tape then worked my way up to building a frame from scratch. If I can do it, my guess is that anyone can. The biggest trick is being able to realize when you're in over your head and asking someone for help rather than proceeding blindly and getting yourself into a real pickle!
