Business plans are the tool existing companies use for execution. They are the wrong tool to search for a business model.

Build and they will come’ is not a strategy, it’s a prayer.

Using the Product Development Waterfall diagram for Customer Development activities is like using a clock to tell the temperature. They both measure something, but not the thing you wanted.

At the end of the day, you can decide whether you want to be an employee with a great attendance record, getting promoted to ever better titles and working on interesting projects - or whether you want to attempt to do something spectacular - this be or do should be a question you never stop asking yourself - for the next 20 years, and beyond.

The world is run by those who show up not those who wait to be asked.

My advice was to start a policy of making reversible decisions before anyone left the meeting or the office. In a startup, it doesn't matter if you're 100 percent right 100 percent of the time. What matters is having forward momentum and a tight fact-based data/metrics feedback loop to help you quickly recognize and reverse any incorrect decisions. That's why startups are agile. By the time a big company gets the committee to organize the subcommittee to pick a meeting date, your startup could have made 20 decisions, reversed five of them and implemented the fifteen that worked.

You need to ask yourself, ‘Where do you want to work: startups, mid-size or large companies?’ If you find yourself debating the ‘startup versus large company’ choice you’ve already chosen the big company. Entrepreneurship isn’t a career choice it’s a passion and obsession.
