What you're learning will fall into different categories, physical, mental or a combination of both. They will employ their on strategies to help them stick. I put language learning in the third category. Anki + srs for memorising vocab, When recalling vocab and phrases, mnemonics etc there's tonnes information online nowadays.

Something you won't hear often is this tip: Try and action/gesture what you're trying to say before you say it. I have no explanation why this works so well when learning but it's a technique actors use when embodying a character.

Then the obvious tip is to practice with native speakers,

If you have something purely physical, you have * Mental rehearsal of the action (anki) * Execution of the action in practice. For this to be helpful you need feedback, you could use a coach or record yourself * performance - like in a sport.

Had to rewrite my response because I went to heavy on the language learning tips

This is what I've used to date
