The evidence of your vivid imagination? (Life is bland w/out being imaginative while you have so much). Of the fact that your only problem is that you've NEVER come across REAL problems? Your 0,00000000001% of the REAL deal, REAL problems, REAL issues?
Have you ever traveled the world? There's many places, you know. Come visit them. If you don't know what destination to choose, just ask. You will see for yourself and THEN and only then you'd have something to compare to. That would change your worldview DRASTICALLY.
