When I was younger I wanted to be an Astronaut or Deep Sea diver.
Went to college and did business studies as it was quite general. I should have done Astrophysics or some science, but didnt get proper advice.
Left college, built a racing car and got sponsored for two years. Was crap at racing. But I ended up working for lots of motor racing teams. Sounds fun, but the money was pants, pay cheque would bounce or you would be laid off at the end of the season.
Then worked for a company that built handmade racing cars you could use on the road. They went bust in the 90’s recession.
Then I got in to accounts / finance, as it was more stable. Did years in that as using excel and double entry book keeping is logical.
Got bored, left and opened a motorcycle shop. Hated dealing with the public and suppliers so sold it. Took almost a year to run out of money.
Got back into finance. Had good and bad jobs, ended up being paid off from one and took about two years out with a massive chunk of cash.
Became a dive guide in Egypt for a year. Brilliant fun, but no money. Then worked as an expedition leader for a marine conservation group for a year. No money but sort of rewarding. Then went diving off Sudan for months and months looking for wrecks till my money ran out. Flipping exciting and flipping expensive.
Now Im working in a brilliant company doing finance.
Ive done lots of different things and realise that my ideal job wont pay me any money to live on. So Ive found a proper job that does, but its also a great company to work for. So that pays well enough to live well, but keeps me interested at work.
Sure, its only finance, spreadsheets and stuff, but compared to the 30 odd jobs Ive had its pretty good.
You have to be realistic. Change jobs till you find a good one, they are not all crap.
Also working at what you like as a hobby may end up killing why you liked it.
