That might be the best investment you can make . . .
I'm talking about monetary though
monetary investments are dangerous. outside of the typical 401k i'm very leery about investing in anything. i dont like losing money and for that reason alone i dont engage in things that has a chance of me losing.
invest in businesses u can start on your own. what do u know how to do that people may pay for? market that. get a website. take it from there.
im sure most people on here will disagree with this, but i've yet to meet any regular person who made it rich or made any significant money from investing.
