Love hurts

How can one improve? It is a daily struggle I have. I feel like I'm improving and I think I'm improving, but I am apparently only kidding myself. I do things better, or spend time improving myself, so I feel that there is forward motion in my self improvement. But, something is still wrong. I seem to forever displease Master. This is a battle I will continue to fight, as I want nothing more than a safe, secure, loving relationship with Master. But it hurts my heart that I feel like I'm doing good, but find out that I am not.
