Why is number 1 calling us?

It's not just a number: it's the principle.

If you chose 1 or if he chose you, it's no coincidence.
You are that person who doesn't wait for the go-ahead: you've already started. You lead, you decide, you invent. Sometimes they follow you, sometimes they don't - but you go anyway.
You have the head hard enough to open new roads and the heart big enough to believe in it first. Yes, even when it seems crazy (indeed, especially then).

1 is the number of pioneers, of visionaries, of those who know that loneliness is only the price of the first step. It is not just a number: it is an attitude.
It's your way of telling the world, "Don't worry, I'll start."
