Glad to see you had a great time at the McCartney concert. Definitely cherish the show and the memory. The good thing about concerts is that when you are a old in your years - you'll remember that show and seeing the greatest songwriter of all-time.
You certainly won't remember the Algebra, Geometry, or History classes or the tedious and boring job
That's why you always make the time to see events such as concerts rather than the everyday garbage mundane chores that you may do every-day
