If you think in simple terms, everything in life is reps. If you want to get better at anything you have to put in the time, the practice, and repeat. You don’t learn a new skill once and then you’re good. You need to put in the work. The reps. The repeated practice to ingrain said skill into your brain.
It doesn’t matter the task. Studying, training, learning a new skill like playing an instrument or developing a technique in sports – whatever it may be. You need reps. The habit of repeated practice.
But, reps may not be enough. Ask yourself: am I practicing correctly? In other words, practice may not make perfect if you’re practicing wrong.
