What a classic song though

Anyone else feel like they're still young, but things just keep moving along? Like I never grew up but now a lot of adults I know are young enough to be my kids. I don't know. Getting old doesn't feel like I thought it would. It just feels like more of what I've already been doing.

Exactly this.

I'm not as old as you, but my 30s are soon to be in my rearview mirror, and last time I blinked, I was still in school.

Now I'm mentoring people who were the same age I was when I got started working. Fuck.
- Them: "How do I get to your place in my career?"
  
  Me: "What do you mean?"
  
  Them: "You... Have the position I want eventually. What did you do?"
  
  Me: "Well. 20... No that cant be right... I mean... Yeah... 20 years ago... I graduated college... Then uhh. I'm... Uh..."
  
  At this point either you make up some bullshit or you say it's just experience. Then you realize what a midlife crisis is and wonder if you are having one which like like 20% of the definition of a midlife crisis.
I was sitting on the ground doing a puzzle with my kid the other week. Ended up with back pain for two days. I don't "feel" old until my body reminds me.
"Isn’t it funny how day by day nothing changes, but when we look back everything is different."

You measure your life by the milestones. When your a kid these come quickly. First words, first steps, first day of school, first friend, first crush, and on and on. So many things happening all of the time. As we get older the time between these milestones grows. You work the same job, see the same people, have the same routines. The space between those milestones blurs together and it all feels the same. It goes by slowly, but when you look back it's happened all at once, where did the time go?

It's important to fill as much of that space between as we can. Be adventurous and try everything, hit new milestones.
We're all kids. Growing up was never about being mature, it was about being quieter.
