A study shows that eating exactly seven walnuts a day boosts your brain power. Re- searchers show that spending at least sixty-eight minutes a day doing aerobic exercise is best for your brain. The list goes on. The number of best practices for your brain is long—and a little daunting. Learning how to pick the “better” option in- stead of struggling to attain the “best” one can help. Trying to achieve perfection is the enemy of making progress. Sure, maybe ninety minutes of aerobics a day is ideal, but a brisk thirty-minute walk every afternoon is much better than remaining glued to the sofa. Think of it this way: there’s a poor choice, a better choice, and a best choice. You want to avoid the poor choices, pick as many best choices as you can, and for the rest, go with “better.” It’s better for your brain health if you make some good choices rather than none—or give up because it seems too hard. For example, you know that the saturated fats in cheese make it food to avoid. But if you love cheese and can’t imagine living without it, pick an aged Cheddar. That’s much better for you than a processed slice of goop. When making choices, ask yourself “What’s better?”
