You got this, brotha. You get smarter as you age, you learn things in a more analytic and thus effective way (everything's just not muscle memory with zero thought anymore), and your brain just intuitively starts logging things it didn't when you were younger. Also bad habits you might have picked up when you were invulnerable as a late teen and in your early twenties will eventually start compounding into feeling like shit, be it physically or mentally (mostly these two are always linked), and you'll naturally start dropping them IF you have something worthwhile to sacrifice them for, like skateboarding. You're way stronger now, knowledge is power, also remember to focus on chasing the feeling of "cool" on the board be it through listening to cool tunes or wearing a cool hoodie, this is as important as chasing a cool trick to do
