I thought this short story of a team (a power greater than myself) might help shed a light on this topic and it goes great with your meme. I also at one time struggled with the 3rd step. Actually turning my will over to my higher power is a daily constant. I always find myself trying to take my will and my life back (intolerance). Life becomes easier with surrender and acceptance.
In the Army we was trained to do everything as a team. A team is definitely a force greater than myself. There is no way I could fight a battle alone and be able to win, much less win a war. Especially a war within myself. Granted we are trained to have mental toughness and fortitude, yet we can't win by ourselves. For me, my disease of addiction/alcoholism completely shredded my mental toughness and fortitude. My will (decisions) got me into the war with addiction. Logic says my will (decisions) can win the war with my addiction. What I failed to realize due to my ego is that addiction is definitely a power greater than my self, a negative power but still a power greater than myself. Especially fighting against both my ego and addiction. The disease of addiction and ego would intentionally mislead me and say, "you can do this alone, you don't need help." All along they're both sitting over there plotting and plannning their next several moves, while already having the intel on my next move. The disease of addiction and ego was always two moves ahead of me on the chess board.
I needed a force greater than myself. I needed a team to help fight this battle and the war. I had to surrender that I am powerless to fight this all alone with my own will. I had to surrender to and accept a power greater than myself to help fight a power greater than myself (addiction & my ego). I can't fight this without my recovery/sobriety team and family. My higher power put that recovery team and family in place for me. All I had and still have to do is surrender to and accept them and their help. Thanks to my higher power I can now have hope in winning this war against addiction and my ego.
