Block your insecurities telling you that there's stuff you just can't do, and give everything a try if you think it's technically in your reach (it usually is or you most likely wouldn't even visualize the trick / spot in the first place). Basically come to terms with how the little excuses we're always tempted to find not to try shit are really just cop outs for not wanting a trick that bad. Thing is if you want to see said trick go down the way you mentally picture it, then you're going to have to go and materialize it yourself because no one's going to do it for you, or do it the way you imagine it. I find that to be a great motivator to get the most out of every session.
And even when trying a trick - realizing that not coming anywhere close after dozens of attempts although you know there's a chance you could technically land it only means that subconsciously, part of you doesn't really want to land the trick right then and now (which is OK, sometimes just the process of trying itself is fun), and instead of mindlessly repeating the same mistakes over and over again you really need just one go where you actually really, really want to do it, blocking all doubt in your head and just looking forward to rolling away because, why the fuck would you not roll away? Just a bunch of mental stretching in general, but I believe those are fundamental cognitive matters that really affects how one skates.
Skating with older folks is inspiring when you're young but don't only skate with older folks in your mid to late 20's, as people in the 30+ crowd (which I'm part of) love finding excuses about not being as good as they used to be, fantasizing about their own old achievements or abilities and are basically resigned that they are past their prime like part of them is dead inside already. I skated with people like that almost exclusively for a few years and their energy had started to rub off on me, I was starting to find excuses for not doing hard tricks again and basically, technically regressing. Then I started skating with kids 10 years younger than me again and realized my fuck up, the kids have energy to spare and still more excited than jaded about skating. I quickly realized it was more fun to be in such an environment too sometimes and now that energy started contaminating me instead; got all my old tricks back when I thought they were forever lost, and started progressing like I was suddenly 17 again. Started watching what I'd eat a lot more around that time period too, probably helped. Nowadays back home I mostly skate alone though.
You don't have to skate 10 hours a day every day, your body needs the rest or you'll just ruin it. Off days are a thing and completely acceptable, you don't have to battle yourself for all the entire afternoons you spend skating shitty spots and every kickflip you do rockets. Just cruising around is amazing too.
Maybe a stupid one but, wear clothes and shoes you actually feel good skating in.
