A point I often make to beginners is you can have initial success amongst your peers and more experienced practitioners by learning tricks they don’t know.
The problem with this is, is basing you’re Jiu-Jitsu on isolated knowledge advantages instead of structure.
The above process is due in part to prioritizing short-term wins, poor coaching, and giving in to the idea of shortcuts.
Shortcuts DO exist, but by definition are antithetical to the long haul.
Take the time to do the job right the first time and let the outcome take care of itself.
