I can't tell you how many times I'm up late because of one reason or another. Most times it's because it's the only time I do get to myself to really unwind and catch up on a few things I need to catch up on. There's peace and quite, or at least the lull of snores throughout my home! After awhile though I'm kaput and it's time for me to catch some Zzzzs.
I will admit that I'm a night owl, thus I usually don't go to bed too early. I also am not a morning person, unless I have to be, it takes me until my shower to get me going! After a shower I'm "bright eyed and bushy taled" and ready to face the world!
I know we need to get enough rest in order for us to function at top level daily. I tell my kids that all the time. When I do get them to go to bed earlier than they do sometimes. However, when it comes to school night they know mommy doesn't play around. They have to get 8-9 hours of sleep. There are times when they get only 7 hours and thus wakes up tired, especially my oldest daughter who sometimes get only six hours.
For me, as long as I get four hours sleep I"m ok. Of course I need more rest but since child birth I've learned to survive on a lot less sleep time, and that's the truth! If I ever get less than four hours sleep I would be climbing the walls by 3pm at work! So, even the little four I'm used to, I've got to have them.
Oh yes, sleep is very important. Otherwise writing something that makes sense, especially at times like this, well, stuff just desn't seem to compute, spelling errors happen and a person can fall alseep while typing! [i'm surprise i didn't make a spelling error as I'm walking on my eyelash at the moment!]"
