I'm thirding this here, I'm about the same age, worked in a bunch of different things and technologies, helped startups create their product from ground zero, been to startup events and talks with investors and now I've accomplished my dream of being able to live abroad, out of my home country.

And even then I've not come close to the first hand experience you have now, 7 years driving two companies.

So don't be too harsh on yourself, you're doing very well, way above most of people even in your country.
