I have $400. What can I invest in?
This question and answer originally appeared at Quora.
Don’t waste your time investing in anything other than your own education with that size of fund.
For example, you could use it to buy a number of books in your field that will enhance your earning capacity – and then save the extra earnings and invest that continuously every month.
If this is all the money you have in the world you need to keep it in the bank – just in case, and then save up some more money.
