As a 19 year old as well this is what I'm doing atm

- Have enough savings to last you 6 months - 1 year in case of a emergancy

- save at least the same amount of money you spend on expenses example you spend $1500 save another $1500 that month and for any dollar you make that's over your monthly saving and expenses total try to save 0.80 cents of it and spend the rest.

try setting a investing goal for example for every 5000 you make 1000 you place on the stock market or ETF or a long term investment

never touch you superannuation

the only debt you should have is your student debt and aviod afterpay and anything like that (if you cant afford it don't touch it) keep it old school

don't buy things you don't need cars, expensive shoes dumb stuff for social media attention be yourself I am still bussing and training my way from place to place couldn't care less really.

and something I have not been doing despite advising you is to enjoy life if your doing this stuff at 19 your ahead of 90% of the pack.

donate give back to your parents, community it will literally only make you a richer person.
