Skating is supposed to be easy. Even if I "have" a trick, if I'm still straining to do it, then I'm doing it wrong. You can watch a pro do the same trick and it's effortless. There's no reason mine can't be like that.
And I'm usually right. There's ALWAYS some minor adjustment you can make and suddenly it feels effortless to do whatever you were doing.
Having this mindset really forced me to keep experimenting with weight distribution, pop angles, foot position, etc and it made a huge difference. Plus you save energy in the long run. If you keep bailing on something or landing them 1 in 5, you realize it's pointless to keep wasting time trying again and again without making a major adjustment first.
