A wise person is naturally less anxious. Lots of people are anxious and dislike it so cultivating their inner life could help them with that. Most people prefer to not go that route, it is optional. Nobody is demanding you to grow wise or even that you would be capable of.
But as we grow old, not achieving some things we thought would be easier when we were young can cause frustration. Wisdom helps dealing with that.
