Simple savings/investing that everyone should do:
1. Have an emergency fund of preferably 6 months worth of living expenses in a simple savings account (use Ally or CapitalOne360 as they have the highest interest rate)
2. Invest in your company's 401K at least up to the full match. It's free money, there's no reason to pass up on it. If you can invest up to the max of $17,500, do it!
3. Open an IRA (Vanguard is great) and contribute as much as possible, up to the $5,500 limit
If you are in a low tax-bracket now, you should set up the above accounts as Roth to take advantage of less taxes in retirement once withdrawing.
Got to Bogleheads and invest in a 3 fund simple portfolio consisting of index funds. Invest in the ones with the lowest expense ratios. You should probably have 80% of your portfolio in stocks, and 20% in bonds at this point in your life.
