Because, to be honest, seizing the day can be easier said than done.
It's like adding items to your bucket list with the intention of checking them off. You may write down "take a tropical trip" in a note on your phone with so much excitement, wanderlust, and passion. But, you may ditch the idea when you realize that you have to do a little research, purchase a plane ticket, and come up with an itinerary. You may think, "Well, I'll get around to it," but don't get into that habit this summer.
