Needs etc

I was thinking today about not having updated my photo web page at pbase. In addition, I realised that I haven't spent any time going through my photos, choosing the ones I like, processing them, taking new ones and so on. On its own, that doesn't mean anything, people forget, have other priorities etc, why should I be any different?
The next thought though was a bit more important. I feel like I need to be doing that, taking photos and all that follows. The key word here is "need". Why do I need to do this? It's just a hobby, it won't change anything in my life (assuming always that the International Organisation for Very Talented Individuals - InOVeTI - is not looking for the next Extremely Talented Individual - ExTI), if anything, it will take up my time, my energy, my precious free time. And ok, having a hobby can act as a form of self-therapy, of releasing pent-up creativity, it can help you get in touch with a side of you that's under-represented in your everyday life and therefore you can get extra benefits from spending time on it, but a need?
I'm just curious: If I was a photographer by proffesion, would I turn to other areas of life for my hobbie, feeling that I need to do so? Would I take up accounting, maths, physics or marketing as a pass-time? Would I feel the "Need to Account"?

Probably not.

Therefore a) I'm lucky I'm not an accountant by proffesion (no offense, it's just a matter of personal preference) and b) I should just do what pleases me without going into too much detail about what's the inner motive that drives me.
However, and in response to (b), I am curious by nature. I want to know (but hey, at least I don't need to know).

Tha last thing I want to say is "Madonna".
