Anyone can feel like a failure if they have lofty goals. The #5 golfer in the world can feel like they failed if they never won a major. The NBA MVP can feel like a failure if they never got a championship ring. An EVP of the biggest company in the world can feel like a failure if they were never a CEO.

There are plenty of people in the richest 1% who feel like they failed even though the other 99% might want to trade places with them.

Set realistic goals and work towards them. Don't base your success or failure on meeting every one of them 100% before you turn 30.
