Keep your brain sharp

The majority of people are stuck in ruts. They go to the same job everyday, hang out with the same friends and eat at the same places. While that may feel safe, its not the most stimulating lifestyle for your brain. Those synapses have been built up enough, so try something that you do NOT know how to do, Buy a model car kit, master the art of sudoku or crosswords, or go pick up another major at your nearest college. The point is you need to be learning new things to keep your brain honest. Form new synapses by forcing your mind to work in ways it has not worked before. Just like physical workouts, doing too much of the same exercise will eventually give no results.
