And don't get me wrong, change is of course inevitable.
What does not have to be inevitable is the loss of the skill gained by learning how to work on more things will make you better at working on all things.
The skill of being able to work through what you don't know without breaking, kludging or ruining, parts, tools, pieces or flesh without just replacing things can be invaluable, success begets success, simply replacing parts does not.
