The answers in this thread indicate no really good ideas for fast and legal/ethical so your best bet is to land a tech job and work 6-9 months to get to 100k if you're senior and if you're more junior then probably 1 year.

All other 6 figure professions require massive schooling or certifications/apprenticeships/internships of some kind. Or years to get to 6 figure territory. For tech, you can learn web development online and then work at any SaaS that has CRUD apps as a junior-mid level engineer and start around there. If/once you have experience you should be starting above that.

One viable option is some consultancy that pays for deliverables, not hours and meeting attendance. Let me know if you find a consultancy like this. I think that would be ideal semi-retirement mode, work one 6 month contract each year or something like that.
