There is only one way to become better and better at what you do, and that is to learn and improve every day.
Many people in different professions will tell you that they learn every day. Others will tell you that they don't need to learn anymore. Then there are those who say they learn and learn and know so much more than others. Sometimes it is a mix.
I watch. I see the people who are good and who are what I want to be more like. They all possess one thing that truly does allow them to learn. It is humility.
The more you learn, the more you realise that you know nothing. There is so much more to learn and if we do not realise that, we can not extend ourselves.
Just be open to the fact that you do not know it all and have so far to go. That is the best lesson.
