When I arrived at Columbia Business School, I was delighted to discover that every subject was just about solving problems. Instead of explaining things, we we always expected to propose solutions. Of course, the problem with business school is we seldom had the opportunity to execute a solution, and even if we did, we weren't around long enough to see if it really worked. 

When I look back, I realize I have often gotten hung up on my solution. But now I've found the right perspective… there's always another problem (and sometimes it's coming from our solution).

Love the Problem, Not Your Solution

It starts with a fundamental mind shift. Your customers don’t care about your solution but their goals. Identify the problems or obstacles that get in the way of their goals, and you identify the right solution to build.

Having more passion for your solution than for your customer’s problem, is a problem.
