Do you remember when you were younger and you couldn't wait to become an adult? You couldn't wait to stay out all night, go where you wanted to go when you wanted to go. You couldn't wait to have your own space and maybe even have your own space. Well, with adulthood comes bills, work to pay for those bills, responsibilities to take care of your place, take care of yourself, and keep your loved ones from going crazy with worry about you. You might have loved ones whom you are responsible for, also. All of that sounded like it would be fun to do when you were younger. It was a thrill, just to learn how to drive. It's still cool to be an adult, but it's also a big juggling act.
For now, your might just be juggling school, work, your family and a maybe a significant other. Life gets more complicated as time goes on, but you have a lot on your plate when you are in school and working. School is a big deal, because your education and work ethic will give you the skills that you need now and later in life. You might not even end up with a job that's remotely connected to your major, but the all of the stress and pressure that you learn to overcome while keeping your grades up, is grooming you into a go-getter for the world out there. I personally believe that it's great to work while you are in school, because you get a sense of fulfillment from earning your own money. You learn how to work with others, and you learn how make a living and manage your money.
Don't forget to have fun, and don't have too much fun. Maybe that's the secret to balancing it all. Have fun, but still remember that you have a job to do. You have a future to build. You might even have people depending on you. So, sneak in some fun here and there, but not the kind of fun that you'd regret later. Go to the movies. Go on a short trip. Go to the club (if you are legal). Exercise and go to the doctor and the dentist. Pray, go to your place of worship, meditate, or simply have and keep your personal faith. The key to life is about balancing and taking care of yourself, physically, spiritually, and mentally.
