What he said. Just that you are thinking and considering your options now at your age, puts you FAR above the majority of people.
There is a TON of info on this subject, and obviously some people feel you should do it a certain method, and others another method. ( Traditional vs Roth, percentage invented, into what type of funds, ect ect )
