ON THE Second DAY OF CHRISTMAS, DAMN EARLY DAYS GAVE TO ME...
A single sentence worth thinking about.
You will never have more life ahead of you than you do right now.
Let that sink in for a minute.
For all those dreams, for all those ambitions, for all this thing you want to do before you're gone, you will never have more time ahead of you than you do in this moment.
That should be all the motivation you need.
