Can you recommend some things I should think about and/or investment opportunities I should consider (e.g. 401k, Roth IRA, etc) and how to decide where to start?

I am a college student and want to identify a smart way to start saving money. Can you recommend some things I should think about and/or investment opportunities I should consider (e.g. 401k, Roth IRA, etc) and how to decide where to start? I already know the basics about my 401k and Roth IRA. Any other thoughts suggestions about additional investment opportunities I should consider would also be helpful. Thx!
