I like to celebrate my birthday. It is something that is important to me.
I do not do it because I want the attention or things. I do it because I like that I am alive. I like to celebrate my birthday to honor all of the things I am, do and will do. I celebrate to honor my past and future. All those that I have met and will meet. All the things I will have experienced or will experience.
On my birthday I get to celebrate ALL of the things that make me me. Most other holidays you only get to celebrate a part of you. I get to celebrate the macabre side of me on Halloween, the spouse side of me on my anniversary, the family side of me during most other holidays. My birthday is the day where I can be all of me, not just a tiny part.
A lot of people get hung up on the number or year that they are celebrating. In my mind that is not worth celebrating. Getting stuck on the number is only going to get depressing. There are not many ages worth celebrating. 16, 18, 21… Great, you can drive, vote and drink. People dread 30, like it is the end of the world. More dread 40, like it makes you old or something.
I think you should be proud that you have been around to circle the sun 30, 40, 50, 60, on and on times. Each rotation adds knowledge, skills and experiances. Things you can pass onto others, or horde for yourself (if you want.)
Celebrate being you for another year. You have chances to accomplish things. You can take care of anything that you will regret later. You get to have experiances.
You are ALIVE!
