Yeah life speeds up hella scary. And I don't even remember 99% of my life so far, like - it just fades to black after a while with some split memories here and there which aren't probably all that accurate. Meditating 20 minutes a day does slow it down though, as where time is lost is when you're stuck in your head all day. 

Halo I thought you were 20 something already, I was just in my 1st year at uni at your age so don't worry you're already doing half of the shit already. The other half will be an endless cycle of failures that will sooner or later form into some kind of manageable set of compromises with life's demands and your want to sit in PJ's and eat cheerio's.
