Wisdom isn't about the ability to make a hard decision. As it is used in the Bible, wisdom is understanding how life works. It's about understanding who God is and what He does. It also includes understanding people, other people as well as yourself. And there is the overlap of these two categories: how God interacts with people and they with Him. Being wise is having a measure of understanding into all these various dynamics. It's understanding how life works. And being wise is important because the insight that it provides makes living well a possibility. So, being wise is not about how to make difficult decisions. Being wise is about how to live. It's about how to navigate relationships. It's about understanding why you do what you do, both the things that lead to your happiness as well as the things that get you into trouble. It's about knowing what to expect, knowing what God is going to do next. Being wise is about living and living well.
