Re: Cultivating a mind for training honestly.
Here is a trick I use.
Make Uke do the proper action first. So if the action is push nage so nage can throw hikiotoshi, then before you practice the throw, practice Uke's part.
Then go to the throw and repeat. Make training Uke's part as important as Nage's, not just the fall, but the attack as well.
When I started Kendo I thought it was odd that the higher ranking person received the technique first ( playing what we would call Uke). Then I realized what an advantage it was to have the "better" student provide the proper attack first. This sets the pace, and shows how Uke should be generating the attack.
