Plays with your head when the numbers start getting so big on paper.

This quote and synopsis comes to mind

10. "In investing, what is comfortable is rarely profitable." — Robert Arnott

At times, you will have to step out of your comfort zone to realize significant gains. Know the boundaries of your comfort zone and practice stepping out of it in small doses. As much as you need to know the market, you need to know yourself too. Can you handle staying in when everyone else is jumping ship? Or getting out during the biggest rally of the century? There's no room for pride in this kind of self-analysis. The best investment strategy can turn into the worst if you don't have the stomach to see it through.

Truly, GLTAH and have courage !
