Have you ever wondered why there is day and night?

Yes, I have thought about it several times and I got one answer every time. The answer is there can't be the existence of day only without night and night can't exist only without day. Both exist in pairs.

I'm the one who is now looking for a way to reduce my love for sleep.

It's a common nature of most of us which makes us lazy but it's not a problem because I think it mostly depends on other work. If you have many things to do, then those work won't allow you to sleep how you want.
