If you wish to, you can. Climb on a roof and extend your arms out. Feel the gentle wind brush past your skin. Close your eyes. Imagine Titanic. Hold that fantasy for a while. You can.
Fill your backpack with a set of earphones, a drink of your choice, a sweet little snack, camera, book and pen, and go for a nice walk. You can.
Make some art with inexpensive paint and invaluable imagination. Make a phone call, knock on a door, go pick a bouquet of flowers, and give it to the next person you see. You can.
For just a few hours, look at the stars, admire the city lights, make a new playlist, study a city, buy new boots, write a letter, nurture a plant. You can.
But you don’t, you won't, and you complain that you are unhappy. When you can just do, what You can.
