Does life end after 35?

There will always be people who remain curious throughout their lives, as there will always be people who stay close to what they know because they believe it to be safe.

Yep, that's the infuriating, "catch 22" aspect of the whole thing. There are things you want to do at a certain age, in some regards, but you can't for whatever reason, but then when those reasons change, you've lost that time for good.

I feel the same way to a point... I couldn't have founded the startup I've founded, when I was 25, because I didn't have the technical knowledge, the business knowledge, the general maturity, etc. But the flip-side is, I'm getting older and I kinda look at this attempt as probably my last "at bat" with a chance of really living out the most exuberant of my hopes & dreams for life. I feel like if I fail now, I am probably done with big dreams. There just isn't enough time left on the clock, and I won't have the energy and drive and passion to start over from scratch.

Most of my ideas and entrepreneurial thoughts as I got older tended towards the more complex rather than the opposite. I never, in a million years, would have thought of Instagram. Not in my mental framework. In fact, I probably would have discounted it as a dumb idea. This is to say that there can be value in approaching entrepreneurship from ignorance (not meant as a pejorative). I would say that most of the things I've done that did well are things that, in retrospect, I jumped into with such utter ignorance of the reality of doing that thing that I probably would not have attempted it had I known. That's what I mean when I say that there's value in ignorance.

Now, a little bit about the programming business. Being a programmer is like being a supermodel. Once you reach a certain age, if there isn't something particularly special about you your career prospects can and often do change. In certain circles (SV being a good example) older programmers have a hard time finding work. It is a young man's world. I know many who moved out of the profession or relocated for this very reason. The issue of age discrimination has been discussed many times on HN. It is real. Keep that in mind as you go forward.

There's also another issue. Thirty years ago one could be an entrepreneur and, later in life, go get a job somewhere if needed. Today, things can be brutally different. With entrepreneurs generally plastering their lives all over the internet there is no dumbing-down your resume. No way. Which means that your life, your achievements and struggles will follow you forever. If, as you get older, for whatever reason, you decide you'd like to get off the entrepreneurial train and just get a job for a while it could be tough. People google your right away. In certain domains you'll run into FUD. Middle managers will not want to hire you because they are afraid you might be after their job (after all, you are very capable). Small to mid business owners will be afraid that you might want a job with them to learn about their business and later go off and launch a competing business. I did not realize this was going on until I had a chance conversation with a recruiter who was telling me about one of his customers who simply could not get hired to save his life due to his very public entrepreneurial profile. Obviously someone eventually hired him. Apparently it took a tremendous amount of work and time.

You are 35. Nothing to worry about so long as you don't stop learning. Just be smart about it all.

But it happens the other way too, in that many young inventors tackle problems because "they didn't realize they were 'impossible'". More knowledgeable folk can do this too, but it requires a certain... disrespect for authority. Like Einstein's flexibility with time and space (though he was young then; he didn't make breakthroughs in later life, possibly because he himself became an authority).

Fortune favours the delusional.
