I'm not sure I agree with this:
"First and foremost, an idea is never world-changing. It's the execution of the idea that changes things. Until it has been executed successfully and actually changed the world, all it is is an idea. The impact can only be assessed later."
Frankly, I believe ideas can be quite impactful. Think of any math concept. Weren't they ideas? Where's the execution? Or more philosophical terms, such as panta rei, "The only true wisdom is in knowing you know nothing.", "communism" etc, aren't those ideas?My point is that I think boundaries are not as defined. Unless we spend some time defining "idea".
but on the general "stop whining, start doing" underlying message I do agree 100%.
