Welcome! Rather than think of 'the next 30' maybe just focus on right here, right now, in this moment, today...I know it sounds cliche, but really, looking so far out is self-defeating - at least for me, the thoughts of 'never again' seemed so unattainable that the thinking 'why bother' was always an easy excuse in early sobriety.
You'll find that many of us here had lots of hobbies and interests that took a back seat to our drinking - only for those interests, and new ones, to develop and blossom.
The thinking that sober = boring is only as true as we allow it to be.
Take care ~
