Also as hard as it may sound i would suggest ignoring your goals and just focus on getting better long term. Once you reach your current goals you won't feel done but will simply move your goals further.
As it was beautifully said by I don't remember who. Some people solve a cube once and they move on with their life. Others think "oh OK. I solved it in 10 minutes but maybe I can do it faster. " if you fall in the second category (as you clearly do) the mindset never changes. Only the times you consider fast.
I started cubing with a goal of being sub-30. Now being 15.x on average I am still haunted by bad habits I established to get sub-30 as soon as possible.
P.s approaching 40 I'm also considered an older cuber
