Became a dad and lost the part of myself I actually liked

Son is 3 now and I genuinely don't know when I became this person. Used to play in a band, go to shows, sleep till noon on weekends, make spontaneous plans. Now my personality is just logistics and exhaustion. Don't get me wrong, I love my kid more than anything, but I miss feeling like myself. Miss the creative part. Trying to figure out how to be a good dad AND not completely lose who I was before all this. Any dads figure this balance out?
