I am a member of a classical guitar message board, and we do indeed sometimes have a somewhat similar situation there, with people who have never played an instrument before, and now they have endless questions about which brand of guitar they should buy, which brand of strings, which electronic tuners, should they play with nails or not, should they spend ten minutes per day practicing scales or fifteen, and so on and so forth, and some of them just never learn that music is made by a musician, not by fancy equipment, and not by rigid sets of rules. For them, indeed the best advice would be to just go practice a bit.
Perhaps we should have a sort of unwritten rule here that if you want to ask questions about inspiration and what kind of pencils to use and so on, you should include a link to your sketchbook. If you can't draw, then all advice you need is to take a sheet of printer paper from the printer, take a common old HB pencil, raid the kitchen for an apple, egg and coffee mug, and draw what you see.
I am of course biased, because raiding the kitchen for subjects to draw is what I am doing at the moment, to the virtual exclusion of anything else. :-)
Gotta say though that drawing such humble things has already greatly attuned my eye to looking out for light and shade and tone, and also to the sheer beauty and intricacy of absolutely everything around us.
