Your mind is right now filled with old thoughts. Not only old thoughts, but mostly someone else’s old thoughts. It’s important now, it’s time now, to change your mind about some things. This is what evolution is all about.

It is always the individual who thinks. Society does not think any more than it eats or drinks. The evolution of human reasoning from the naive thinking of primitive man to the more subtle thinking of modern science took place within society. However, thinking itself is always an achievement of individuals.
