Life Milestones

Are there any absolute, common for all age milestones on our life timeline? I think many people reflect in that direction. I fell there is something of that kind, and that I have passed two of those milestones.

The First Milestone.... Although probably our first milestone was someplace there, at a very young age, but we do not realise that consciously, and infants do not need that vanity at all. OK, my first milestone is 21. When I turned 21 I felt some incredible lift-up. I thought I could do everything I would want, any kind of undertaking. I found my future wife in that age and introduced my girlfriend to my family (believe me, all of those who knew me by that time were in shock). Over the years, growing older and meeting failures I started thinking that one can achieved nothing in his life at all, if started later than when he is 21.

The Second Milestone - 40. It has been more that 6 months since I celebrated my 40th birthday, so here is what I happened to collect of what I feel.
- desire to live in an absolutely white (walls) room, with minimum of items around (a computer table with a wheeled armchair, a TV set, audio/video players, obligatory shelves for my discs), no curtains, no pictures, no chandeliers....
- my teeth somehow began causing me troubles
- I want to get rid of useless items, and have sold several discs and "The Beatles - Anthology" book already
- I get so tired quite soon
- either the lack of practice (I don't remember already when it was that I went out of our home in the evening) or anything different, but I experience problems while singing (I start feeling discomfort in my nasopharynx)
- after I come home from walking anywhere other than "to work and back" I feel very tired
- when I am sleepy (both at home and at work) I put everything aside and sleep
- my old fears became my advisers
- many of what I accepted earlier is being criticized now
- the feeling of lifelongness of punishment for my life failures much amplified, it now does not imply any hope to get some feeling of forgiveness in this life, and after - it does not troubles me somehow (there should be something that I already lost due to my failures)
- if nothing has been created by me over a day, I can feel it dying in my hands
- I decided to start blogging

There should be something more, but I do not remember now. I do not force anything to stay in my head if I do not need that.

What next?

P.S. Here is another interest: could it be that when we were infants we were shown some key images from our future, remembered them at subconscious level, and now, when we follow our life paths and check with those milestones by means of deja-vu phenomenon, we wonder "this already happened in the past!"?

Meanwhile, I keep on remembering some details.
- my already-not-such-high speed of playing strategic games became even worse
- I no longer love bright sunlight and hot days
- success and achievements in different areas do not bring me joy, but fade when Sun goes down

Full circle is about to close, and it becomes so hard living endearment-less....
