Unless you thrive on punishing yourself, you will need to learn to balance your academic, business, and personal lives. This may not be easy to accomplish, especially for those who work full-time and have families. Hopefully you are already in control of the time you spend at work so the concentration of effort to balancing your life will be spent between academics and family obligations.
I made a decision when I entered graduate school that I would not put my family through the extreme absence of my time like they endured when I was an under-grad. To that end I dropped to half-time beginning with this quarter and will continue this schedule until graduation. This measure has afforded me the opportunity to spend more time with my family. Yesterday we took the morning to travel to another town to check out a house because we really wish to leave the town of our currant residence. Today, my daughter spent the morning and afternoon playing putt-putt, and riding go-karts and bumper-cars. I was still able to complete my assignments and discussions for the week and all the submissions were on schedule.
The total time spent on course-work for this week was about 24 hours. On a full-time schedule that would have more than doubled and I would not have had the opportunity to spend the quality time with my family. We would also not be able to move if I was participating in a full-time schedule. As it stands, in order to move I will need to complete my course-work for that week by that Friday in order to have the weekend off.
