There are two things you should never, ever go cheap. One is the mattress you sleep in at night. You should be getting 7 to 8 hours of sleep. If you get 8 hours of sleep or if you are in your bed eight hours a day, you are in your bed 1/3 of the day. Invest in a mattress that will add to your life and make the next day rested and relaxed. Second is the mode in which you work. Be it a desk chair, a car seat, or the pair of shoes you wear because you are on your feet all day, invest in those things to make sure that your work day is as comfortable as possible. If you sit in a desk all day, invest in a great desk chair. If you are in your car all day, get a great car with great seats. If you are on your feet all day, invest in the best pair of shoes. Invest in yourself so that you are your best self.
