Y halo thar, iPower!
It may be common knowledge, but I think that if I underestimated the effects of this, a lot may not be as well-informed. I'm talking about sleep, and more specifically lack thereof. Let's just say that the effects go far beyond "just being more tired the next day".
More often than not, during that dark period I went through, I didn't sleep much. I felt that time was a scarce resource. As a result, I didn't want to go to bed. I felt like I didn't have time to do stuff I wanted to do. Does that ring a bell to some? I'm sure it does.
Thing is, sure, I stayed up... But with no will at all to do anything whatsoever. The normal motivation level someone would have would go AWOL, made me quite irritable, and unbeknownst to me, it made me fat. Yep, if you still eat normally, not sleeping makes you fat.
Net result: lots of time completely WASTED, ironically, for the sake of SAVING time.
I've noticed a difference when I started going back at the gym. I took sleeping hours very seriously as I wanted muscular tissue to repair and grow as optimally as possible, and I've noticed improvements much faster than I expected. However, during the last two days, I've been constrained to sleep only 4 hours per night.
And goddamn, do I feel like an unmotivated mess or what?
And that's when I figured it out. Not going to bed because of gaming, internets and all kinds of shit like that was one of the main cause of a plethora of issues.
When you can compare the improvements you've had by actively taking care of this versus how you feel when you can't have all the sleep you want, you see how important it is.
So those 4 hours you "wouldn't have" because you go to bed earlier will upgrade your next day's hours with motivation, positivitism and energy the next day. Much better than having 4 extra hours of fuckall at the end of your day.
As I said, sounds like common sense, but sometimes, when in a vicious circle, common sense can't be taken for granted.
