Education is important for your life and the lives of your children. You will naturally set the standards for what has value and what wont have value in your life. Education is only one thing out of many. Some will choose immediate gratification to buy the things they want while others will delay that gratification for more knowledge. If you are going to spend money on an education then it is beneficial to stay focused to maximize your return.
What and and where you spend your money says a lot about you in the same way as where you spend your time. If you are crunched over your video game for 6 hours a day or out fixing your car every moment you can afford then you are obviously very interested in games or your car. The same can be said of your education.
Those students who make it through have persistence because they have the willpower to stay at it day-after-day and year after year until they get to the end. Those who want a degree but couldn't care less about the education will focus on the degree and grade while completely neglecting the higher responsibility of learning.
Staying focused means spending your time and effort on learning instead of wandering into other activities. Each person is different in this respect. Some are capable of balancing their time and energy while others do not have this ability. If you are having a hard time with distractions then cut them out completely so they are no longer pulling on your attention strings.
Getting ahead in life is not easy and does sometimes require sacrifice. There are things that will come easy and there are things that take more time. If you have the right skills and your research and writing come easy then you obviously don't need all the time someone who doesn't have these skills will need. Be honest with yourself, stay focused, and be diligent with your efforts.
