I'm a little late but here goes. Growing up my dad was a mechanic and I've had a wrench in my hand since before I could walk. Being blessed with good common sense and an engineer's brain (maybe a little dose of OCD thrown in for good measure) I've always had a hard time paying for something that I'm fully capable of doing. That extends to the circle of people around me (friends/neighbors/girlfriends/girlfriends friends/etc.) My take is that I try and make it a learning experience. Let's do it together, I'll show you how to do it right, we'll have fun, drink a few beers, then compare busted knuckles afterwards. Then next time maybe they'll pay it forward and teach someone else when they feel that they have the skills. That's been a fairly successful approach thus far. Sure, there's been a few folks that want me to just do it for them and (college girlfriends excluded) I've just directed them to a reputable mechanic. If they aren't interested in learning about their ride and what makes it run then I'm probably not the best person to be wrenching on their rig (my hourly rate is way too high).
There's also been a time or two where a simple repair has turned into a project that was either above my skillset or my toolset. But luckily those have been few and I'm never too shy to say "I don't have a friggin clue". Because I'm definitely not an expert by any means. Of course as I've gotten older many things that I used to do myself have now been "outsourced".

LOL.
Keep up the great work w/the YT channel. If it helps folks do their own thing, it's way worth it!
