Look around you: I bet you money that most of the stuff which surrounds you, the things and services you interact with and quite possibly a large(r) amount of your possession are not that exciting to you. They are replaceable. They are there to be used and then tossed away.
It’s the same with most startups and the products or services they produce — they often end up being replaceable.
We live in a world where almost everything is worthless and a very few things are exceptionally valuable.
Focus all your energy on creating something which becomes exceptionally valuable to your user. When you achieve this — your product becomes non-replaceable, regularly used and truly valuable.
