A stick can't flex unless one end is held strong. Some ideas are basic, are foundational. Being adaptable doesn't mean you have to give up the the things that give you roots, and a strong footing. It's hard to bend when your feet slip with every move. Tolerance accepts others, but it accepts the core of who you are too.
Flexibility is adaptive, alive and strong, and it works in perfect harmony with a strong foundation, self-confidence and self-esteem.
