When there is so much to work upon attentively, one may lose motivation sometimes. One hour of unproductivity grows its reach to become one day of procrastination at work. It continues to spiral until an individual does something that motivates him to become better with time.
The word career is often used to refer to a profession, occupation, trade or vocation. A career could define what you do for a living and range from those that require extensive training and education to those you can perform with only a high school diploma and a willingness to learn.
