To me (and i'm sure to many others) DID has much more implications & meaning than DO in some ways or another. Not trying to be smart but if you carefully step back, relax, juggle with facts and perspectives & put your mind scanning radar on time as a whole concept - it will come to you, just as rain falls and radiation burns it back up into clouds.
I'm 52, divorced, on foot, unemployed... happy as hell - somehow, retired from the grand scheme of social undertakings.
Got 250,000$ many times over, spent it.
Drove a Mazda RX3, coded bazillions of scrap lines in C for anybody who'd ask and pay for it, sold bricks & mortar bags in public - all stuff of the past.
Present & today is key to my hopes & plans. Tomorrow is a never loop which won't hit our lazy foot steps until we run towards some personal goals; in my case latest being, just playing Twilight of the Arnor and developpping Mods for it.
My liberty is a result of some choices made, my fortune and current bank account of context and Oil companies greed.
I regret Nothing of Anything like a well known Quebec's Diva sang in the 30's.
Cuz, no matter where & when anyone is in time, if they didn't
do what they wanted to do... life's natural luck has simply skipped them over for a very good reason.
But, i certainly will. Like i should or not.
