Most of the time you have a problem, look for a solution and solve the problem.
Occasionally you will see a great solution and then have to find the problem it solves. The key is, even if you find the solution you need to find expertise in the industry where the problem exists because to think you can be an expert in an industry you are not familiar with. Too often people think they can develop expertise in a field they know nothing about and that results in huge disappointments.
Just something to think about.
Have a great day!
