With all the information that is freely available, and with all the things you can easily learn, it can really feel that you know it all. If this idea is crossing your mind, a huge red flag should go up. Because from there, it is a small step from thinking that you know it all and with that, all opportunities for new ideas are gone.
It can help to think about it this way: everyone around you knows something about a topic you don’t already know. It is your task to figure out what this is to learn and gain new insights.
Having a mindset like this can really help grow and deepen current relationships and view them from a fresh angle. It definitely helps keeping you with both feet on the ground.
