Mary Meeker’s Internet Trends report is an institution. It’s worth a read if you’re in the venture capital industry and I find that it helps me make 1-2 good decisions as a product exec in a good year.

It’s tough being a founder. They don’t teach it in school, incubators and accelerators notwithstanding. The only sure path to being a good one is having the capacity to learn quickly on the job. You have to unlearn a lot too – you have to stop being an expert at everything and pretty good at a lot of things. Like Marketing, Sales, Product Development, Hiring, Legal, etc.
