The important thing is to save rather than spend everything you earn! Stow your loose change in a container, roll it when you have a lot, and deposit it in the bank. Take a set amount each week to transfer into a savings account even if it's only $25. When you have $1,000 (maybe less) buy a solid stock that shows a 4% or higher return and keep it on a reinvest to buy more. Shop for the best deal and make sure any fees are practical for you. Be conservative at first by looking at a company's track record instead of jumping on the popularity wagon.
