Yup. I do the same - the majority of my losses were/are all ones that i had a decent profit upon, but was stubborn and didn't want to take a small 1% to 3% to 5% gain when I had more.
So, then they turn into losses. It's definitely something that I have to learn still. But when I look back, my entries are always pretty darn good, so if I can keep that up, and just work on exits and the psychological aspects of it, I'll do fine in the long run.
Best of luck!
