Sure, you can. It’s best not to rely on supplements such as nootropics to give you that boost in brainpower. There are a lot more things you can do, such as: Exercising Reading Solving puzzles Taking up a new hobby Traveling and seeing different places These are all things that won’t take up much of your resources, so you might as well give them a shot. I especially like researching hobbies that I can totally get into.
