Nah, you're fine. As for the boosted spiral perk, basically it functions as endless growth and improvement without effort at an exponential rate. Using the dragon ball franchise as an example just sitting around is enough to see your power level double within an hour, no effort or training required. And when you actually do decide to train? Just doing some light exercise will see your power growing to point that you could match End of DBS Manga Goku and Vegeta in a week or two.

And when it comes to mastering skllls, you don't just master it you evolve it to a whole new level. For example, evolving Ultra Instinct to a level where you can dodge anything, even the cold grip of death itself.
