A mental trick that I've started using to value recovery more, both between sets of A+A training and from training session to training session, is thinking of recovery less as a passive process than as active "metabolic work time."
So my training is "doing mechanical work" (which of course involves metabolic processes, but I ignore that in this mental framework). Then my recovery is "doing metabolic work."
This way, I can think of recovery not just as time I'm NOT doing something (lifting stuff), but as something I'm actively doing. I can ask myself, "Am I putting in enough metabolic work time?" And I can answer, "No, I have to 'work' harder!" Then I'm not being lazy by resting more, I'm actually doing more work.
It's a semantic game, but it has positively affected my attitude toward recovery.
