There's something to be said about the person that thinks they have it all figured out. What do they have figured out exactly?
If you have it all figured out, haven't you become an evolutionary dead end?
The only way to continue to grow is to continue to learn.
I love the fact that I have nothing figured out and I always have something to learn. What differentiates us most as a species isn't our race, class, or gender. What differentiates us is our life's teachers and how we seek, ascertain, assimilate, and apply the knowledge we have earned or were given.
I realize that race, class, and gender play a huge role in the knowledge that most readily finds us and the knowledge we most readily seek, but as we uniquely define our world, and as we uniquely define ourselves (as something more than our race, class, or gender), we must not forget to keep that definition dynamic.
You know only a small sliver of what there is to learn, don't be afraid to let what knowledge you find change and innovate you. But most importantly, don't be afraid to keep learning; don't become an evolutionary dead end!
