You're smart to do this. I did the dot-com thing in the 90's into 2000, and thought the money would last FOREVER ... after a bunch of cars, $6,000/mo apartments, ridiculous and WASTEFUL spending (like renting out movie theaters for friends instead of just buying a ticket, lol), guess what? The money ran out.
It won't last forever -- regulation can fuck up porn in a heartbeat, you could go to jail over something stupid, etc, etc.
I congratulate you on realizing this, and insulating yourself, so you're not just another dumb kid who had it all, and now is begging to sleep on someone's couch.
Just make sure you balance it -- remember that, being "semi-retired" in your 20's is special. If you go into a mode where you work ALL the time, it's just as bad -- you WASTE a special opportunity to do what you want while you're still young and healthy enough to do it.
I'd suggest picking up a 3-day work week, and having a completely separate apartment or PC for a "work" environment. I used to actually get dressed up to work in my home office, it made me respect the "work day" a bit more, when I was building up my sites years ago. Also, it helps to have a "schedule" -- work from noon to 4pm, for example, and KEEP that schedule like it WAS a job.
Of course, as you know, none of these suggestions are necessary if you can self-motivate, but it appears, like me, you don't always do that.
Something that also helped me was having friends or family members call and "check in" with me at night, asking what projects I completed, etc. By feeling responsible to a third party, it helped to stay on track.
You might also consider, if you have a good amount of money coming in every month, putting $10,000 to $30,000 away each month into less-than-liquid investments, that discourage you from buying that Ferrari or the latest toy. Lock yourself up until 30-ish, but leave yourself enough so you can take a hit of 6 months to a year with little revenue. Even when I was raking in the cash hand-over-fist in the "good old days," there were always times when multiple projects got fucked simultaneously.
Good luck!
