In your personal opinion, of your own situation.
If you fall into, Hobby like I do now, pick a percentage that applies to your income. If you use Microstock to pay for travel, make an estimate. If you have some other use or way you use the money, like gear and not lifestyle, but I suppose gear is, hobby, lifestyle or entertainment? Make up your best answer, that applies to how you use your Stock Photo Income.
This poll you can change your answer, you don't have to vote to see the answers, and there is no deadline end date. Things can change.
