BEING SPECIALISED OR DIVERSIFIED?

I really want to do some artworks because of many new ideas (which are leaving me because I keep delaying) but here's the clutter on my table that's preventing me from doing so. All these are posed for using or ready to sell on my accessories shop but I'm just extremely slow, mostly in adjusting photos in Photoshop, taking photos and writing descriptions - the worst of the lot. Of course this is just a small portion of what I've done so far (and haven't done). I shall make it a point to draw something tomorrow, an ACEO at least.

The problem is I diversify too much and end up not being specialised enough to excell in either. An ongoing debate no less on the Etsy forums and I do feel it is better to focus your energies on one craft and marketing works better that way too. I have tried and unable to do so because of my varied interests, I'll lose momentum soon enough if I keep on one specialised job, thus a different endeavour will enable me to maintain that interest and recharge while working on another. Does that make sense (cents)? Naturally everything piques my interest, so making a mental note that I shouldn't waste time trying to try attempt everything helps... for a while!
