It makes you introspective. If you lost a huge opportunity than it’s fine to be a day introspective and think about why things turned out the way they did. If you have to restructure everything in your life because you just lost your wife to a traffic accident, it’s can even be useful to spend weeks being introspective.
If you are finished with that introspection, sadness doesn’t offer added value.
Then you want to switch to an emotional state in which you can take action. Being angry at a loss and not being accepted at a company can provide the motivation to work hard to prepare for your next interview.
You can also switch to joy and just let things flow.
That said, for most people it’s unproductive to think about what emotions they should feel. It’s much easier to just accept the emotions that come up instead of fighting them. Then your brain does the job of choosing appropriate emotions.
