I spend the first 10-15 minutes of the morning quietly meditating so that I can cast out all anxiety. I know it makes me sound like a spiritualistic hippy or something, but trust me, meditation works. Personally, I like to use the Stop, Breathe, & Think app. You select how you're feeling at the present moment and the app suggests different meditations to try and center yourself.
Next, I write down what I wish to accomplish during the day. Whether it be small tasks like getting to school early or larger ones like finishing a paper, writing down what I want to get done makes me feel even better when I can cross each one off.
I usually hate exercise, but this is one of the few things that gets me motivated for the day. I use the Sworkit app for 10-15 minutes each morning. The workouts are in 30-second intervals, so the time flies by and makes your morning speed along.
This is the most important aspect of my mornings. I pick out a great, interesting book or article to read for 10-20 minutes over a cup of coffee. It's critical that you pick out something you're interested in, or the reading will send you right back to Snooze Town. If you can't think of a book, look up an article on NPR or even BuzzFeed. Getting your mind flowing early in the morning will make your school work seem less dull.
Right after I change out of my jammies and into my regular clothes, I crack open my journal and write some stuff down. It doesn't have to be world-changing ideas, just whatever's on my mind. If I can't think of anything to write, I have another journal with 300 writing prompts. Again, it's critical to get your brain used to working in the morning, or school is just going to be even more miserable.
