Hardest thing to do in life Forgive and let go! We all have things that happen to us that are unfair and hurtful. I can tell you with reasonable assurance that one of the hardest things in life is do is to “forgive” one another. There is pride that swells up saying I am right and that person is wrong, and I am hurt and can’t that person see that? Give a listen on one of my latest singles. I produced the single about 5 years ago and just one person who I submitted it to said it was so bad that no one will accept it. So I held off for these years based on one person’s reply!
