I find this conversation interesting and relevant to what my eldest is currently considering. He's going to start apprenticing as an electrician in a couple of weeks.
Around here the big money as an tradesperson, even as an apprentice, is working in camps up North. He can very reasonably expect to be grossing >$200k/year by the time he is about 22. The tradeoff is that he'd be going up to work in remote camps for 10-20 days at a time, 18 hour days, then having a couple of weeks off and repeating the process. Long, miserable days, no little amount of danger, and lots of lifestyle dangers (booze and drugs).
For a 19 year old that's fine and something of an adventure. For a 35 year old with a family that is misery. For a 55 year old you are probably already dead or might as well be because of poor health and substance abuse issues, not to mention the divorce(s) and the alienated family. Having worked in those environments myself, none of the above is an exaggeration.
I've told him that he should by all means go work those jobs while he's young and motivated. Make boatloads of money, invest it all and either FIRE outright before he's 30, or transition to buying/opening an electrical company with all that cash he's made. Just make sure to look around at all the older people at the camp and think very hard about whether that's a life he wants to get stuck in for 25 years. Go in, have a plan, make your cash and then get the hell out.
