Jake Owen celebrated three years of sobriety this week, and he did it with a very inspiring message on Instagram. Here's what he wrote, "I'm still working on me, but I'm proud of myself. I also am here for ya if you need anything. I'm also so grateful for the people and friends who have supported and given me grace. I love y'all. To anyone struggling or feeling like they're not enough: remember that progress is still progress, even if it's slow. Be kind to yourself, and don't let yesterday's mistakes define your tomorrow. As the saying goes, 'Every day is a new beginning.' Take a deep breath, smile and start again."
