In my 6 years in the startup industry, what I have found is that luck plays a huge part in being successful. A lot of people that are successful are successful because they caught the market wave. Not because they did something different or were better than other entrepreneurs. Some are truthful about it, but many aren’t. And they always find ways to rationalise their success. It similar to people explaining technical analysis of market graphs. They will provide lots of reasons based on patterns, but it’s all just mumble jumbo.
