You wouldn’t start something if you thought it was dumb.
But sometimes, after you’ve embarked on a path, you realise, “this is dumb”.
But you’ve already publicly committed, invested time and money.
What will people say?
You can’t go back, can you?
Yes you can.
The alternative is wasted time, money and effort. And even greater reputational damage.
That’s a terrible way to spend your life.
If it’s a dumb idea, stop.
