I would say keep your job and invest in an investment plan with a reputable company. The company has access to more money than you would probably ever have, thus has access to bigger and better investment opportunities that you would probably have by investing on your own.
Secondly, invest in reits and ETFs that are popular in your country.
Lastly, do a side hustle that you enjoy and use some of your salary to fund it.
Quit your job only when your side hustle exceeds your income.
Do share your advice. It can clarify your own thoughts while helping others, and all good comes back to you, someway, somehow...
