i think you'll get a lot of disagreement in the tarot community whether reading for ones self is "good" or "bad". it's up to the individual, like so many other apsects of the tarot.
personally, while i do read for myself, i will often project my wishes into the meanings, as opposed to reading what is there. and this leads to misleading readings. knowing this however, facilitates open mindedness on my own part, with interpretations. in other words, when i read for myself, i take my interpretations with a grain of salt, and take more of a "i'll wait and see" attitude. after the events in question manifest, i'll go back to the original reading, and review my notes, adding actual outcomes to my original projected trends.
luv and light,
