The Philosophy of Birthday Countdowns

Here's a thought:

Every day you live is both a countdown to your next birthday and a count from your last.

You're always in the middle of a birthday countdown.

Today might be:

• Day 47 since your last birthday
• Day 318 until your next birthday
• Both simultaneously

Which perspective makes you appreciate today more?

Your birthday comes once a year. But the countdown to it happens every single day.
