If you are not a born entrepreneur or do not have the family business to take over or do not have the mindset or experience to start with something that you love on your own, then do a job and side hustle on your passion.
Save money and keep some money as non-touchable as deposits/investments.
Save enough that you can survive and can have a good lifestyle for at least 2 to 3 years even without any income.
Until then the only way we can pursue our passion is constantly nature it. Keep watering it.
There is no need to quit the full time job you are doing. Do the best you could do for the moment. Just spend some time or keep making small progress on something that you love.
Once you have that security money saved that could provide you the safety net, then commit more time on working on your passion that you love and spend more time on the thing that makes you feel alive.
Now start working on it as if your life depends on it.
You got to commit, dedicate, be consistent, have discipline to keep going even if the world is against you. That is how you achieve your goals and live a life that you feel proud of.
