I'm sorry. Two little words, but it's a phrase that's often hard to say. If you have trouble owning up to your mistakes, know that you're not alone. "We have internalized from a young age that if we ever feel out of control, or unsure of ourselves, we should take great pains to hide that fact from others," says relationship coach Jordan Gray. "Societal conditioning tells us that to be a man is to be confident and correct in all that we do." But the inability to apologize can have a disastrous effect on your relationships both personal and professional. So learning how to do it properly is a skill every man needs to master.
