A Little Bitter Makes Your Whole Life Sweeter
Proverbs 27:7 says "One who is full loathes honey, but to one who is hungry everything bitter is sweet." A counterintuitive truth is that a life with too much sweet becomes bitter, but a life with a little bitter becomes sweeter.
People are resilient. They tend to adapt and become accustomed to whatever circumstances life puts them in. Because of this, a life of too much ease creates weak men. If you want to be happy, strong, and able to withstand whatever curve balls come your way, you're better off seeking out challenges and hardships in measured, controlled doses before truly hard times come and knock you on your backside.
