In order to find the solution to a problem, it often takes trial and error. Sure, the first thing might work but not always.
Trial and error requires you to be willing to embrace uncertainty, take risks and persevere. However, often in life we’re not willing to do those things as much as we could or even should. And so our problems remain.
It has nothing to do with our problems being difficult or challenging. Instead we simply aren’t willing to try something that might not work, so we simply don’t try at all.
