Special Days..?

I don't seem to feel them anymore, the special days like Christmas, Birthdays etc. They seem like normal days to me now and I don't think I'm alone. Let me explain: The birthday symbolizes a child's mentality of an event so significant that it is worth looking forward to consistently, believing that the next one will be better than the last, when in reality the effects of the event dull until it is simply another day.
Why does this happen? Children are always excited, hyper, active and generally joyous. Why does this often slow or even stop? A friend and I discussed this, and she says that it's up to the person whether a day is significant or not and also that it is them who makes it significant. I then said to her does this mean that it is all in your head? Let me provide and example: My birthday is December 19th. So, like most people, I celebrate. Sure it feels great but there is no unique feeling specifically to that day, but that's not the point. The point is if my birthday was August 5th, December 19th would be just another day right? So you see, it's us humans who assign this special event on whatever day of out choosing. There is no actual significance it is only us saying it's my birthday!
If we didn't remember our birthdays, would we feel any different on our birthday as appose to any other day? Hardly.
It's somewhat sad that we must tell ourselves "This day is special!" when really it's not. It is almost as if we lie to ourselves, we fool ourselves into thinking one day is greater than the next. Eventually as children grow up, the feel it. They don't consciously say "Hey my birthday is Lame! It feels like yesterday! I don't feel any older!" (well maybe sometimes they do). They usually feel it subconsciously. Subconsciously they start to notice it feeling dull, like any other day, but they don't know why... at least not consciously. During the time when a child feels so excited about an event that an adult finds almost insignificant, they display true ignorance and obliviousness. Sometimes I wish I could fool myself into a child's mind, to share to ignorance. Back when I was so Immaculate, attentive, Joyous.. and the like. Even though there is nothing significant.. they feel otherwise. Why? Honestly I don't think they would feel much of anything if we didn't make a big deal about birthdays, but we do. We constantly say "What do you want for your birthday!? What do you want to do for your birthday?!".. and so on. This is, even though we don't realize it, a trick. We are fooling the little ones into thinking a birthday is a big deal. Sure great to be alive but there is truly nothing different about it. It is only when we age, and "mature" that we notice there's nothing different. So continuing, I sometimes wish I could be in a child's state of mind, when my birthday was amazing, when there was nothing better than Christmas, when I was on top of the world again every time I became a year older... etc. However, I cannot. There are many forms of this thought. I can think of it as wanting to be a child again, I can think about it as wanting to be old, or to be consolidated.. or whatever.
But I cannot.
I cannot.
The only question is this a positive thing.. or a negative one?
Here's something to reason with:
Reality is just what you perceive it to be, so perceive well...
