<prompt> Human: One of the tips I see around here pretty frequently is that you should have a secondary income stream e.g. freelancing, small business, etc.I think this is great advice, and I want to get started on this to boost my savings, but Im not quite sure what to do.So, rpersonalfinance, what do you do for extra income?EDIT: A little more info about me if it matters, Im 22, been working for 8 months. Work as a marketing analyst for a Fortune 500.  <response>: I make about eight cents a day with AdSense.Im new at this.
