Don't just be a "tools experts". I have been into software development for over 10 years and in last few years I realized that what we developers sell and hone is the skill of being an expert in a set of tools. Tools that allows us to translate the so called requirements into software. We need to be more than that, we need to understand the real world and its problems and get out of our digital shell. Learn other stuff, read about physics, logic, maths, philosophy anything that allows you to think about things in different ways and expand your mind. In the end, don't try to be the smartest guy (the world already is filled with pseudo intellects) , rather try to be curious (about anything and everything). One more thing, whenever you meet someone smarter than you, don't be just in the awe of it rather realize that here is your chance to know more and learn more.
