Hi, tantal,
Yes, we all have our "problem" areas, I suppose. For me it is entries, for you it is exits. You sure said a mouthful here re learning to trade, ". . .but Jesus what an expensive and time consuming process." Ain't that the truth! Kind of fun, too, though, don't you think?
I do find evolving as a trader involves growing as a person, as well. The process of identifying (and hopefully overcoming) one's demons in trading (often repeated in "real life") forces one to explore one's shortcomings. IMO the hard part is in defining the problem; overcoming it is just a question of strategy and tactics.
I am a firm believer that if one's goal is realistic, one can overcome all obstacles provided one does not give up.
EDIT: I found it was pure joy when I opened a daytrading account at IB at a /shr commission, instead of siebert's /trade costs (I still keep that account for large position swing trades as it's actually cheaper in that type of trade). With IB's pricing, commission is no longer a consideration to me as far as exits go, and you may find the lower costs improve your exit strategies.
