The title says it all. Being able to own it is not an easy thing to do. But if you can keep that mentality that you have that control over whatever you are doing, you are probably going to achieve what you set out to do!
Look at Pyrros Dimas. He probably knows he is able to lift the heaviest he can lift each time he steps on the platform. That's why he gets it over his head and owns it.
P.S. this post was actually inspired by the song "Sexy and I Know It" by LMFAO which was repeated non-stop and could possibly be heard during my wedding. Enjoy!
