Think about the last time you tried to get into an exercise routine. Or consistently wake up earlier. Or quit smoking. None of those things are complicated, but all of them are hard to accomplish. We don’t fail at them because they’re complicated, we fail at them because we don’t prioritize them and think about them (let alone do them) on a daily basis.
Customers aren’t looking for features. They are looking for solutions to a problem, and your entire product or service must solve that core problem. Features can, at best, solve a subsection of a problem, but once you start down the road of “wouldn’t it be cool if…” you’re no longer dealing with the big issue.
