RUNNER UP
I didn't find any great inspirational quotes about RUNNER UP. All the quotes I found were against being a RUNNER UP, highlighting that RUNNER UP is first to lose.
But RUNNER UP is actually a great accomplishment and often a necessary step on the route to being a WINNER.
Most of our competitions that matter are a series of continuous tests. We liken life and our major goals to a MARATHON because it goes on for a long time, not because it is a singular event.
And to ultimately win you must play multiple times, practice and refine your approach, and play again. Being a RUNNER UP is likely along the way to being a CHAMPION.
If you have ever attained major grant funding you probably had to be a RUNNER UP first -- submit the grant that scored well but didn't make it, and learn from the feedback to win the next time (or 2 or 3). That is what it takes to win.
