<prompt> Human: Title pretty much says it all. I have no debts and good credit 750. I want to make a serious effort to start becoming more fiscally responsible with my money. Any advice on what I should do?I have about 3k in savings and another 3k invested in the stock market.  <response>: Plenty of good financial advice already in this thread. Take care of your body. Not just your 30 yr old will thank you. All your future self will thank you.
