a) You tell me something you desperately want to be good at and make a commitment b) I follow up with you on a regular basis (email/phone/video), track your progress and send you reports occasionally
1 People that desperately want to be good at something are delusional because thats is just a dream they see themselves already there but they do not have the key to unlock that door.
2 when people go and see someone to help them out in something they want someone to fix that for them otherwise they would be fixing that by themselves.
3 People like that are emotional strugglers they have mental blocks they do not follow up.
4. If a third part is going to make them to commit into something they will be blaming the third part for their failures.
Personally, I wouldn't pay you for that, simply because (as people have rightfully pointed out), I'd want a mentor to help me improve at things, not a human alarm clock. 90% of what you mention here could be automated with a free program, and the other 10% wouldn't be all that useful unless you had a decent amount of experience in the field I'm trying to learn.
In this scenario no one is selling you knowledge--instead, you're forcing yourself to be more motivated. And you make money by taking a small cut when a task gets accomplished, so you have a financial interest in your customers succeeding.
I guess you would have to establish credibility.
e.g. If someone wants to be a great actor, but you have no acting experience.
I guess you could play the matchmaker role. I know there are coaching services out there, at least one that is 'startup-y', but prob plenty more room.
How much do you have in mind?
