Like @bone I like to set bracket orders (OCO stop-loss and limit target) to avoid micro-managing. If stop-loss and profit targets look much too tight after the fact, then to me it just means that the trade was planned on too short a timeframe.
That said, if we're talking about the psychological issue of "letting winners run" then the answer isn't technical, it has to be psychological as well. I would exit just half of my position at my comfortable point and then force myself to passively watch the other half as a learning experience. (Still with a wider bracket of orders in place because I never trust that I'll be available, or have Internet access when I'll need to.)
