If you want to be an entrepreneur, unless your business grew gradually over years as an extension of your hobby, you will have to get through The Valley of Death.
I am in The Valley of Death now. In fact, I’m in the early stages of walking this journey. For me, The Valley of Death is the fact that I left a stable career to pursue a more creative path that better matches my skills, interests, and personality.
This valley means going from plenty of income flowing in to something more modest. This has been a greater psychological shock than I expected. I estimate that for people pursuing entrepreneurship any time later than their early-to-mid-twenties, this will be a real shock.
The Valley of Death is the financial (and other) opportunity cost that anyone experiences when they leave a good, paying job to start their own venture with uncertain prospects and reduced income in the short-term.
So be ready.
And then muscle through.
