Your experience sounds like the life of someone with Uranus at the midheaven: multiple jobs/careers instead of just one, unusual ways of working, but it doesn't feel like you've had any career. (Having Uranus at the MC myself, I know that one firsthand!) You don't have Uranus at the midheaven, but you do have it conjunct your midheaven ruler. Since there are no planets in your tenth house, Mars, its ruler, has the most say... so it's like having Uranus in the tenth.
Interesting that you've made your reputation as a fisherman. Tenth house is, above all, about your public reputation. Career gets put there because for many people, public reputation includes your career... you're the teacher, or the accountant, or the doctor, or the fisherman. But the tenth house is much bigger than career, and not everyone makes their reputation the same way that they make their living.
Looking at your chart, it seems plain to me that you need work in which you're doing something, not just sedentary. Maybe you need to be very hands on and explore. I imagine that, when you were a teacher, your students found you lots of fun, you came up with unique ways to engage them, even if it resulted in a lack of classroom discipline.
I'm not sure how fisherman would fit with your tenth house picture... not what I think of when I think of Aries or Mars or Virgo... but fishing is very active and hands on, so maybe that's it? Neptune and Pisces are what I would associate with fishing... I notice that you have a trine from Neptune to Saturn in Pisces. If I'm not mistaken, your Part of Fortune is in Pisces, too.
Is recreational fishing a thing where you live? Could you perhaps be a fishing guide? If people would pay you to take them fishing, then you'd be making money even if you don't catch anything.
Is there a way you could turn fishing into an educational thing? Do schools in your area do field trips? If so, could you perhaps offer a field trip where you take students out on your fishing boat (sounds like you have one)? It could be a way to teach science, how tides work, what kinds of fish are around and how they live, that kind of thing. And bring the teacher along and let him/her handle the discipline.
