Well put. Just wait until your 40's. Or wait until you have kids! (If you plan on that). Sure, the list may get longer, but once you have that feeling of time is running out - that's when it gets freaky.
My wife and I had this discussion over the weekend. There's the rotten underbelly of tech that is overload and burn out. Personally, I'd love to walk away from tech. It has great money attached to it, but a lot of the time it's not worth it. If you're single with no responsibilities, it can be the best thing ever. You can meet like minded people who don't want to leave 'campus' and everyone can build their life around the job.
But if you have a family, it's probably not the best industry to be in. Sure, some places recognize this and allow for 'flexible hours'. But for most of the companies I've come across that are 'family friendly' this means working late into the night, which means you're tired the next morning. Rinse and repeat.
If I could give the 20 year old me some advice it would have been to apply at Netscape when I had the chance. :)
