Abundance
I have mentioned previously about the benefits of living in reality and truth.
Another example or focus would be the full integration of what Covey calls the "Abundance Mentality" in his Seven Habits book. This mindset is one that is able to applaud others' successes because it does not see the world as a zero sum, "I win, you lose" or vice versa game.
And of course, the world is not a zero sum game, so an abundance mindset would be one grounded in reality and truth.
After 45 years, I have learned one way of acquiring, maintaining, or returning to this mindset - recalling, and then trusting, the element of time.
Having an abundance mentality does mean that you believe that everyone succeeds at everything, every day. But it does mean that there is more than enough opportunities for success for everyone as you we through life.
In summary - freely congratulate others, because their time is now, so let's celebrate that now - and your time will come.
Many times.
