Edit: Baggage removed.
Time changes some things, hopefully my impatience and naivety, but the desire for a 100% flexible job never changed. This time around I want to focus more on what I can actually do to help people, rather than the end result: money. So I've seen many people talk about doing what you know or going for niches closely related to a passion. There are a few fields in which I could actually help; language studies, weight loss and cooking. Then there's passions like writing, literature and music. (I also love to help people in general on the condition that I don't dislike them.)
I'm fluent in 3 languages and have a certain knack for learning the correct pronunciation quickly. Some experience teaching, but not very extensive
As far as weight loss goes, here's the thing, I lost about 80 pounds without following any diet, training program, having a personal trainer... and I'm pretty sure I can explain how to do the same in a cohesive way, but! it's not the "instant fix" most of the target group seems to be looking for(and will honestly most likely never find... I guess there's always lipo). Also I hear that it's such a competitive market that I would need the backing of McDonalds to be able to make a splash. As for cooking it's the sort of thing where I started early and just kept at it.
Just to make this crystal clear: I'm not asking for a complete business model, simply a nudge in the right direction. I have been researching keywords and niches, but the competition always seems overwhelming. Is it a case where simply bracing yourself and going for it is the best course of action? Also I just got a job in sales both to finance the often fruitless starting period, as well as getting some first hand sales experience... thoughts on this?
Sorry for the long wall of text.
PS. If you disagree with the whole "going with what you know" concept, feel free to chime in regardless!
