Your Brain Needs Reps

Your brain runs on the same rule as your body: use it or lose it. The skills you lean on stay sharp, and the ones you ignore go rusty. The good news is that a focused 10 minutes a day is enough to push back.

Here is the part most people get backward: your brain gets sharper from the strain, not the comfort. A drill that feels a little hard, the kind that makes you concentrate, is the one paying you back. Easy repetition keeps you where you are.
