Has anybody put significant amounts of time into finding their purpose / passion? If so was it successful and how did you do it?
It usually comes at random after doing certain tasks and you find that you "love it", I've found that I have a passion for trying different food from all parts of the world, but I don't think I can actually land any job with said passion

Anyone here making TV show about different foods of the world?
My passion changed during different moments of my life, As a kid, as a kid of aroun 6-7 years of age - I enjoyed building different things with lego, making remote control cars, sketching and making miniature replica's of different things with match sticks.
At age 7-11 I increasingly practiced sketching and painting and won 6 gold medals and a few silvers medals from art competitions against different schools. I had also competed in chess competitions and 100m dash - which I've both lost

Turns out I had relatively short legs to be a fast runner.
At age 11-12+, my father helped me build my own PC, and I found I enjoyed it a lot as a hobby - but couldn't imagine doing it for a living, so naturally got interested in software as well - so I started studying myself, I started doing what script kiddies do.. writing some really non-sense scripts that serve no purpose, I also enjoyed gaming - I'd join MMORPG, use packet sniffing and find exploits and use it to do stuff you aren't meant to do and got banned form a couple of games.
In summary, just TRY OUT A LOT OF THINGS.
I am now about to graduate doing a course on Software in University and already have almost 2 years experience working in the industry... Already got quite a lot of jobs lined up to choose from and all with relatively high salary relative to what graduates usually get.
edit - I still practice sketching regularly and hope to publish a graphic novel at some point (hopefully).
