Are there any other investing methods I should look into?
401Ks and IRAs are types of retirement accounts. They have rules regarding maximum amount of investments per year; who can invest; destructibility; and the tax treatment of the growth.  Stock, bonds, mutual funds, ETFs are all types of investments that can exist either inside or outside of the retirement account. Some 401Ks restrict the type of investments you can have, others allow you to own almost anything. Any investment is a risk, and there is no guarantee that it will grow.  Look around the site for beginning investment advice. You should start with the 401K offered by your company especially if they have matching funds. That is free money. Many suggest you invest enough to get the match, then invest with an IRA. Look into IRAs because under US tax law you can still make a 2013 investment up until tax day 2014. Take the time before tax day to decide on Roth or Regular IRA.   The more exotic investments take more time to understand and should not be a concern until you have laid out your basic retirement accounts.
