So it is clear that attachment to positions is exactly the wrong mindset. I have a difficulty conceptualizing the idea of detachment because detachment is not an active state. It is more of a passive state. I'm a man of action so I had to come up with a way to turn detachment into a proactive and constructive state that would lead to profits captured, rather than profits mourned. So I have come up with the mental picture of Maximizing. Marty Schwartz identifies this state with hearing the cash register ring.
My definition of maximizing is to make the most out of the positions that are open, or to do my best, though that doesn't quite capture the essence. The outcome of having a maximizing mindset is that I am constantly on the lookout for a good or decent profit, and am always looking to make the most of those open profits that I do have. The object isn't perfection, but rather to do the best you can. I would much rather cash in a decent profit when there is a hint that a pullback might be imminent, rather than waiting for the pullback and exiting at an inferior price.
In order to fully accept the concept of maximizing as a valid way to trade, I had to accept the concept that what the market does while I'm not in a position does not affect me. Since I am all about maximization, I accept the decisions I make in the heat of the moment, rather than looking to see what happens next (after the position is closed) as either a vindication or a rebuttal of my trade exit. This takes me out of the coulda, shoulda, woulda trap that is so easy to fall into, and that serves no constructive purpose (because in reality you can't "shoulda done" anything, or in other words you can't change the past - so why worry about it?).
I also had to accept the concept that any amount of profit or any amount of loss is a good profit or loss, and is acceptable. I had to visualize myself taking many varieties of profits and losses and accepting those outcomes as good, acceptable and OK. In other words I had to become accepting of my new "maximized" trading results, rather than viewing them through the 20/20 hindsight lens of unrealistic expectations.
Think of the alternative. If you don't accept your trading results - let's say that you reject a small profitable result. It is then likely that this rejection will lead to freezing up and not taking small profitable trades, which may lead to small profitable trades turning into losses. If you reject a loss greater than some amount, then this can cause you to freeze up or not be able to act when the market gets to your stop point, or past where you think a small loss can legitimately be taken. Bottom line is that lots of internal strife can be created by not accepting your results, whether they be losses or profits, and that internal strife will tend to sabatoge your trading at the most inopprotune moments.
And maximizing is fun. These corny, silly little profits and losses all add up to daily and weekly results that make me smile. After I started maximizing, the fun came back to trading and my P&L started improving dramatically. The market tends to retrace, so maximizing profits in the here and now makes a lot of sense, especially if it might just be going to retrace later. Minimizing losses makes sense too, because there is no sense in riding a losing position into a larger losing position. I don't like losing positions. I like getting rid of them as fast as possible. They are like the hot potato that I quickly toss to the next guy before it can burn my fingers.
So the mindset of maximizing coupled with flexibility is how I try to approach trading when a position is on.
