His influence is really strong on you? Do you feel he’s a bit controlling or pushy at times? Does he have a “my way or the highway attitude?” Just because you consider someone your best friend, doesn’t mean that you blindly follow their advice. Where is your own confidence? You need to develop some trust in yourself as as well. You know yourself as an individual better than him. Have some faith in your own decisions as well…he’s not always going to be right. A lack of confidence on your part could be a part of the problem here.
