Too much of anything is not good for you. Not enough of something is bad for you.
We are all creatures of habit. We do the things that we do and stick to it. We wake up and goto work at the same time. We take the same route to work. We do the same things at work and get off at the same time. We come home the same way and watch the same shows. We will eat the same thing at the same restaurants.
When we do this it saves us from having to think. We made a decision previously for what the best thing to do is. Very Rarely do we go back and question these decisions unless we are forced to.
Staying in the same patterns will always get you the same results. If you are perfectly content then keep doing what you are doing. If you are not then it is time to change it up. Start small by changing your alarm clock by a minute or two. Change what side of you mouth you start brushing your teeth.
