Apple's Success
Deciding on a strategy (irrespective of the complexity) is extremely hard. Sticking to it with “unwavering dedication” is even harder - especially when the going gets tough.
See, in the good times, it’s pretty easy to sit back and be content with one’s existing strategy, because there’s no reason to re-think the decisions you’ve made in the past and the direction you’re evolving in now. But when the shit hits the fan, it becomes much more difficult and second guessing becomes second nature.
I believe real entrepreneurs stick to their guns, but only long enough to realize that they need a bigger gun. If things aren’t working out, then eventually you need to wave that extreme dedication goodbye and pick a new challenge.
