I'd say that it's not always the best thing.
Let's say that we speak about the possible career choices. One would think that having a variety to choose from is a good thing because everyone could (theoretically) find the place for themselves and a career that they are going to shine in their full potential. But when you come to the choosing point which criteria are you going to use? Too many possible choices needs more criteria points, and then you can easily get lost in over-thinking. And even when they choose one, there is always going to be that doubt, could they do better with another choice.
For people who are prone to complicating rather than simplifying, too much of possibilities is never a good thing.
