I posted my biggest obstacle here Saturday: When I started my business in 1983, needing the money was my biggest obstacle. I had a good job, which I left on purpose; and mine was the only income. And we had heavy debts left over from business school, and four kids, 10 years to one year old.
There was also a biggest boost to starting a business: My wife said “go for it; you can do it.” And she meant it. At several key points along the way, she made it clear that we would take the risk together. There was never the threat of “I told you so, why did you leave a good job, you idiot!” What she said was “if you fail, we’ll fail together, and then we’ll figure it out. We’ll be okay.”
If you’re starting a business and living a relationship, then think about that one. Call it a “make or break” factor.
