If you rely on faucets earnings for your daily spendings you either live in a very poor country or you don't have any idea on what you are talking about. There are signature campaigns in here that can pay you up to 0.006 btc or more daily and this for sure in any country is not enough for the daily expenses unless you live in a poor country of course like Bangladesh or Afganistan.

The 2 ideas you gave are far from making a living with bitcoin but it can be done although very difficult to do.
