Mind you.
Today's a fairly short day. I woke up at some time after noon.
I go to bed shortly after midnight. (Well I could stay up until 12:30, but I'd prefer to have six hours and change, as to allow me the guaranteed six hours, rather than exactly six hours which usually means I sleep less than six hours. And having half an hour extra gives that comfortable cushion of extra time.)
Twelve hours isn't exactly the shortest of days, but a usual day is like sixteen to eighteen hours. Sometimes up to twenty, albeit rarely. So the true test is having a day like that.
Yet all of today.
I haven't been tired!
As far as I can recall, no need to nap, no having taken a nap, no heavy reliance on caffeine, no more caffeine than normal (in fact, probably less!), and having had caffeine early in the morning...it has long since worn off (I had it almost 12 hours ago and it only stays in you for half that amount), and yet.
No tiredness.
No exhaustion.
Now, that's not to say there's no problems.
Stress is there, from a self-inflicted hell of my own making. (Basically I undertook a wonderful project, but one which I am simply put...rapidly finding is something incredibly hard to execute.) Fatigue from working on it for three hours straight is there as well; I needed to do something else with the rest of my day because of how much it took out from me.
Guilt's there for feeling like I'm not doing a good enough job, and all of that, but like. These aren't long-standing problems that have been plaguing me forever. This is just a problem which is my own fault for having taken it on and thinking arrogantly that I'd be able to do it far easier than I actually can. (It's much harder than I thought.)
Which isn't mind you in of itself even a new problem; I do that sort of thing all the time, where I start something thinking it'll be easy, a breeze, a cakewalk, but end up learning that it's a ridiculously hard task. One which I hope will be worth it in the end tho!
