I'm 35 and I'm not at all complaining. Career wise, I've not only learned more technically but it seems like I'm learning better/faster these days than 10+ years ago. On a personal note, it's nice to know I'm established with a decent amount in my savings and retirement.

With friends, most of my friends are younger but it's nice to be able to partner with them and go through life shoulder to shoulder. It's nice to know that I have the means to be able to help people too, that alone gives me much satisfaction and contentment.

The nice thing is, 35 seems to be a starting point for me. I've got a long way to go and I'm re-evaluating my options. I used to think that getting older meant that I would regret not having accomplished the goals I had in my youth but now, I see it as refining my goals and I'm walking into things with far more experience and knowledge which means more than just "getting it done" but "getting it done, well."
