One can be making a relatively good living at it (I have spent in the last 15 years close to a $ million sending four kids to private schools and colleges <g>). You should know that you must have the "psychological" make up to do it, namely, you mst be able to look in the mirror few times a day and say, "what I did was idiotic, I must be an idiot" (g). Not too healthy for big egoes (vbg).
