For me, as someone who works full-time, is getting my masters, and working on my own projects, working efficiently, staying motivated, and getting sh*t done is key. Of course, I have days where I do nothing, but having my own ways of keeping the grind going have tremendously helped my life.
They say college is the best four years of your life. While that may be true, there is a lot more to your undergrad than sleeping through 9am classes and attending a Friday night party (or any other night of the week for that matter). College is about earning your degree but it is also about putting in the time to learn and advance yourself in your career.
