If you need help understanding, I'd be glad to explain it further. Tough decisions are tough because the two choices are very close, therefore people take more time choosing. The result of their choice won't have as big of an impact as the ones that are more obvious and take less time to choose. The closer the decision is, the more time we take making it but paradoxically, the choices are so close that it won't have a big impact either way. Do you think that the choice between iPhone 6 and 6+ will really impact anyone's life in a significant way? Rest assured much time will be wasted...ahem...spent on this insignificant decision. Does that make sense? If not, please explain the reasoning behind your decision, or perhaps you'd like to not understand for some reason.
