Interleaving the Different Things You Are to Learn

I think with golf, we want long term improvements. We need to practise what we're not good at and stop doing things we've already done. One thing is varing the conditions of practice, rather than keeping them constant and predictable. And there's one where people's intuitions are wildly off, not just in golf, but in all kinds of sportsmen. You go somewhere to learn tennis, say they will work you on your forehand, and then they'll on your back end and thenserve. I'm looking for those desirable difficulties and really becoming comfortable with the uncomfortable.
