To solve your problem you need to ask how you can solve it—that is, identify various solutions. But should you do so from the get go?
Ask how to solve your problem only if you already know its root cause(s)
Formulating your problem with a how is attractive because it forces you, right from the start, to think about potential solutions: you are dedicating yourself to finding the various ways in which you can solve it. Soon, you’ll decide which one is the best, implement it, and give yourself a pat on the back.
The problem is that much of your effort can be misplaced thinking how if you don’t know the root cause of your problem.
