This is a lesson I’ve learned. When you open a position you do it for a reason. Hopefully you did some research and you have few good reason that support the case to go long or short.
But they are your decisions based on your logic! and when you discuss it with a friend or someone else they have their logic and some time hidden agenda that can influence you in a wrong way. Keep it private. Set an exit point before you even open a trade. You may adjust it during time but again base on your logic and not someone else…
I’ve done this mistake many time before and it cost me money. Big money. No I am silence like a fish…
