My Mrs has now got 500 x $1 sngs under her belt with a 14% ROI and $80 profit. She is a novice, so it is definately possible.
I have to bite my tongue at times when looking over her shoulder, but essentially she keeps it very simple.
I have only ever given her a few pointers (along the lines of not overcommiting pre-flop, not-overvalueing post-flop, patience in relation to stack size VS blinds, a little basic pot-odds etc). All very basic stuff. And she has stuck to that without getting overly greedy in terms of moving up levels, and as a result she has done well.
