Looking for some advice on which track is best for me

Newbie here, looking for some direction. I've done my research but I would like some additional input. I like to write and I'm going to provide a decent amount of details about myself, so if you don't care to read all of that, I will sum it all up at the end of this post.

I love to travel. I've spent the last three years traveling around the United States on my motorcycle. Every 6 months or so I would stop to re-up my travel funds. I worked as a lumberjack on the US/CAN border, caretaker at a vineyard estate in California, and mechanic at a motorcycle rental place in Dallas. I also gain great satisfaction from helping others out and have done quite a bit of volunteer type work along the way. In my ideal world, I would do nothing but travel where ever the wind blows me and help whoever I bump into along the way. Unfortunately, the world runs on money and seeing as I am not independently wealthy, I have to work just like everybody else.

I recently came back to my home in Florida and have realized that I am not going to be able to settle down and get some type of career type job and be happy. What I need is the ability to earn money regardless of location and do it on a very flexible schedule.

Creativity and engineering are in my blood. They are what make me the happiest. I love to build and fix things and enjoy the challenge of problem solving.

My problem is that the tools of my trades (construction and mechanical) take up a lot of space. I might be able to fit all the tools I have in storage into a box truck, but traveling the world in box truck doesn't have the same appeal to me as doing it on two wheels. I'm also about simplifying life, and being able to fit everything I need on the back of a motorcycle has brought me more happiness than I would have ever imagined.

I love to learn. I am always trying to pickup new skills. One winter while trying to not freeze to death in North Dakota, I decided to learn how to touch type and program. I carry a laptop with me and figured it might be the only tool I need to keep the travel funds at a healthy level. I completed an intro into Java programming taught by a man named John Purcell (look him up on Udemy or YouTube if you're interested), but didn't really get any further than that before I was back on the road again. I am currently refreshing myself on all that stuff, but don't quite feel it is exactly what I am looking for.

Through researching the last couple weeks, I narrowed down some sort of web development as something that might fit my bill. I am still unsure as to which route would be the best for me. I'm gravitating towards the front-end stuff currently because it seems like the best place to start and the potential to freelance and work remotely seems to be fairly decent.

I joined Treehouse because I need structure and direction to do this in a time-efficient manner. I have a massive folder full of links to free education stuff, but I am notorious for loosing focus with the massive amounts of things that interest me. I can learn very fast when I'm motivated and have others to challenge me and I am hoping to find some of that here.

TLDR Version: Current motorcycle nomad looking to become a digital motorcycle nomad. Wondering which web development route would the most conducive to traveling and working either freelance or telecommuting on a very flexible (and probably very light) schedule.

Thanks for any input you guys may have :)
