Keep learning

You will never know everything. There will be gaps in your knowledge and understanding. It can be easy to immediately reject things which are new and unfamiliar, but do not fall into this trap. The world continues to evolve and while you don't want to be swept away by every fad that comes and goes, you should approach the new with an open and curious mind. This will not only expand your own knowledge and exposure, but also help you make and keep friends by not getting defensive whenever something new challenges your current understanding. As your understanding crystalizes and experience increases with time and exposure, you can update your solutions and even your principles to better reflect your updated context. You avoid stagnation by re-evaluating your principles and practices. Maintain a growth mindset and don't settle with your current level of ability. Always strive to improve.
