It comes easy to some, not so easy to others. Regardless, if you put your mind to it, anything can be accomplished with a little time and guidance. Whatever the case, don't be afraid to tackle something you've never done before. What is the worst that could happen? 99 our of 100 times, if you screw up it can be fixed. 1 out of 100 times it will have to be replaced. Even if you do screw something up, at the very least you've walked away with some experience, or as BD said "not as ignorant." The more experience you get, the more you can tackle bigger and more complex jobs.
That's why a Haynes manual or FSM is so great: Experience in a book.
