Well if it's working for you then great; sounds like squatting 1.5x your current body weight is the goal in that case. If you want to hit the 1.5x body weight mark, what's stopping you from adding just a bit more weight (like 5lbs) to your next set of squats, or doing more leg work each session, to push towards that goal?
(I'd still say to avoid thinking in terms like "beginner trash", so it doesn't become a habit, but I put quite a lot of weight on how I think about and frame things)
Like letting a field lie fallow - seems like a waste of good farming land, but it allows the soil to replenish itself and produce more the next year. Regular rest keeps the soil healthy; overworking the plot drains it of all its resources, leaving it barren. So too with souls (or whatever your preferred terminology; I think it's fair to call someone's creativity their "soul", even though I'm not religious).
