It has taken me a whole two years to decondition myself out of the idea that staying busy is the same as being productive. There was a guilt that came whenever I caught myself in a daydream, scrolling on my phone, or walking for no reason. "Is there not something better I would rather use this time for?" I always asked.
Unless you're training for something where the routine is clear, the target is clear, and there is no expected outcome from the training besides completing the routine, this idea that people procrastinate is actually nonsense.
For people who work in information manipulation—be it trading, data analytics, digital art and graphics, writing and storytelling, AI training and fine-tuning, etc.—there is no such thing as procrastination. If you feel lazy, it is because your mind hasn't computed a satisfying idea yet. The aversion to the guilt that comes with this concept of procrastination can push you to escape through doom-scrolling, worrying, or self-victimization, among other ways you've conditioned yourself to cope with guilt. Most of these mechanisms are so aggressive in the way they grab your attention that even when your mind finally computes the appropriate idea, you will not be attentive enough to notice it. This is why there is a cult of people who believe they get their best ideas in the shower or after taking a nap. Yet, that is probably just the time they are relaxed enough to listen to their mind.
But in reality, if you calm down and stay mindful, your mind will naturally start suggesting useful solutions to whatever problem you have. All you have to do is keep interacting with your mind. If the solution you've discovered doesn't make sense, ask yourself what is missing, and allow your mind to get to work.
Basically, whenever you catch yourself feeling guilty about procrastinating, remember what you are claiming to be procrastinating from, and pay a bit more attention to the nature of your breath as you keep procrastinating. If you do this for long enough, you'll start craving that free time because you'll believe that it is when you get your best ideas.
