Saw some comments about teaching and real estate, that's all it takes to get me going...since I do a bit of real estate mentoring on line. I'm retired and got out of real estate and finance, but enjoy keeping up by assisting newbies. I don't charge for my advice (and have been asked to, good reasons not to) but many do and it can be very profitable. I'm not suggesting to be a real estate guru (I really dislike those scammers) but if you have or can acquire expertise in a business, consultation or mentoring could be a very good way to go.
My students are not in contact with me 24/7, usually just a few minutes on the phone
or some e-mails will do the trick. I saw where someone was doing software
consultation, that's a very good venture.
I established a national presence on various real estate sites and one thing led to another. If you have a passion about something others may profit from, providing instruction on the internet
is a great way to make a living. Unlike providing instruction in a formal environment
with a class and living under a schedule, mentoring can be accomplished on your time, in a series of instructional materials.
I'm no techie, so I have things to learn in order to unplug and get on a boat, but that is my plan as well.
