"I am extremely blessed to have people in the past few years help me build my character back up reminding me of who I am and who I want to be!!!"

I'm VERY aware I'm never gonna be perfect, and I'm gonna keep making mistakes. I wanna be a man that learns from them and grows from them!! I want you all to know this tour has been unbelievable and has taught me so much about myself. I am reminded of how blessed I am to have a voice in this world. I've learned the more you appreciate your calling the more you want to protect your calling."

"Me taking this time right now is me saying I want to be SUSTAINABLE. I want my career to be sustainable, but I also want my mind heart and soul to be sustainable so that I can be the man I want to be, the husband I eventually want to be and the father I want to be."
