How mechanically inclined were you when you first started boating? If you weren't that mechanically inclined, how did you develop the mindset needed to accomplish projects - especially without buying materials two or three times and redoing things? And most importantly, how do you know when it's time to call in a professional?
Not very, but mostly because I spent my employment years doing other types of work... no huge time available for trial-and-error on mechanical stuff. Irrelevant, since you're (appropriately) thinking about you.
Limits change over time. What might be difficult for you today could be easier next week or next year. Knowledge builds on knowledge, so what you learn today could make what you need to learn next week or next year more easily acquired.
Jobs (problems) vary. Some are easier, some more complicated. Many of the more complicated jobs are actually a series of connected smaller, easier jobs. Divide and conquer.
Some jobs only require a few simple steps. If access won't hurt you, those are generally good to start with. Some are more complicated, but if you can find the manual, read and understand the directions, have the tools... and access won't hurt you... those can be good learning/practicing jobs. Some jobs are complicated, might benefit from special skill or tools... and here's maybe where it pays to hire the expert... and then have him teach you how to do that job while he does it for you. Et cetera.
I've found learning the jargon first is critical. What the hell's a "flange?" (A real example, in my life; had to look it up.) Once you know the jargon, understanding the directions is easier.
The manual for a given system is usually useful, usually available online.
Exploded parts diagrams are nifty, and usually available for systems that have several parts. Usually available online from the manufacturer, these days.
You don't need to go from zero to hero in 47 minutes flat. Start now, eventually you'll be comfortable with doing your own work more often... and you'll see your maintenance bills will have gone down. Today's limits don't have to be tomorrow's limits.
