4. Travel and live abroad
Traveling abroad can be greatly beneficial for your mental health and enhance your memory. However, there’s a condition to this lifehack, which is: you have to spend some time staying abroad as well. It might be all fun and entertaining to be a tourist in Cuba, but if you want to expand your mind, you have to live there short to long term and truly experience life there. This will make you more creative and imaginative as well.
