Nobody can predict the future. You just have to give your all to the relationship you're in and do your best to take care of your partner, communicate and give them every last drop of love you have. I think one of the most important things in a relationship is caring for your significant other through good times and bad.
One thing about being a stand-up is it's a one-man show. You gotta do everything. You're the producer, writer, director, and the actor. You just gotta be out there and perform and give your all. It's such an honest form of art that it just taught me so much, and it kind of prepared me for manhood at an early age.
