We'll likely say something today that we'll disagree with years from now and may have never considered years ago.
I used to worry about this when I first started writing publicly. I thought that if I contradicted myself somewhere along the line, people might call me a hypocrite.
I no longer let myself get hung up on this train of thought. If we are hungry for knowledge and information, our beliefs are bound to change. From that perspective, contradiction can actually be a symbol of growth.
Sharing our ideas and engaging others in them is one way to put our growth in hyperdrive. It not only requires us to articulate our thoughts, but it invites feedback, helping us see the world from a new vantage point.
It's better to have an idea, shape it, share it, learn from it, and evolve it than to never let it out of your mind.
