A recent tweet of mine may deserve some proper discussion, let me elaborate it here a little bit more:

Let me also state that this is not a ground breaking discovery whatsoever, but it may help you put things into the right perspective and focus where you need to, especially if you are an aspiring entrepreneur in your very first steps.

An idea’s value is directly proportionate to the time you invest turning it into reality.
Corollary I: no time → zero value
Corollary II: your time is bounded, so is your idea’s value
Corollary III: given your abilities, what only matters is time spent on execution

Simple as that, end of story.
Or actually not. I could go further providing some examples and my train of thought before converging to such a simplistic approximation of an evaluation model, next to its implications for entrepreneurs, but I’d love to hear your feelings and feedback first.
