3. “You are different.” – Compliment his uniqueness
If you tell him that he is unique and better than others, his self-esteem will receive a boost. It is even more effective if you comment when you see him devoting himself to work or to something he believes in. On the other hand, if your boyfriend is an “Average Joe” and is mediocre at everything he does, what do you say? Let him know that you love his sincerity.
