Qui-Gon: "Don't center on your anxieties, Obi-Wan. Keep your concentration here and now, where it belongs."
Obi-Wan: "But Master Yoda said I should be mindful of the future."
Qui-Gon: "But not at the expense of the moment. Be mindful of the living Force, young Padawan."
As a simple analogy: Do not focus on winning the lottery, when you cannot feed yourself today.
Save for the future but you must not starve today.
Today, this year, these are the good old days, if you write down a bit of what you're experiencing now, you might value it highly in the future.
Don't over think it... go outside, get away from the screens for a bit, and enjoy the day, your youth, and the wonder of it all.
