I'd suggest picking up the html/css/Javascript courses:
The Complete JavaScript Course 2018: Build Real Projects!
if you want to get into the app game:
iOS 11 & Swift 4 - The Complete iOS App Development Bootcamp
Wait until they go on sale for like $10-$20.
Decide what you prefer the front end (the logic to handle the graphics - so if you like animations or like what you see on the screen) or the server side (working with organizing data).
From there next piece of
mandatory advice: build a portfolio. From the last step, using either front end or backend skills (or both which is a full stack) make some personal projects. The employers will be looking for it.
That means using the what they taught you in those videos, make some web apps, phone apps or web services: either 2 really flushed out projects or about 5 small to medium-sized ones.
Then start applying.
After about 6 months to a year you'll be more than qualified to start applying and land a $50k-$80k job but has the potential to get you into the $150k range.
Also who knows maybe get a great idea strikes and make a real great phone app that makes a ton of money or a web app that generates a lot of traffic and get paid from that. But at the very least it'll look good in a portfolio.
Regarding tech sales, that's a lot trickier. My brother served a full tour in the Marine Corps, obtained a Bachelors Degree in Math from a prestigious university, was one of the leaders of a frat there and has had 2 sales jobs before - dude is seriously driven, incredibly convincing and persuasive, great with people, persistent and has the resume to back it up. I'm sure you can get in without all those qualifications, but it's tremendously more difficult and you'd have to have an incredible convincing personality (which, is sales).
