I love a good metaphor, and someone shared the perfect video metaphor to capture an entrepreneur's journey:
A fish escapes a tank, makes a treacherous journey on land, and finally ends up in open water.
What caught me most by surprise when I tried being an entrepreneur for the first time was the fish-in-land feeling. Nothing prepares you for that level of discomfort, fear, and uncertainty than actually doing it.
A nice river (or ocean), significantly better than a tank, awaits those who take the risk and make it.
