Be nice to your co-workers, clients, you name it. Listen closely and help them whenever you can.
To me, empathy is the most important skill a programmer should have. Make a conscious effort to understand your co-workers' point of view, your users' point of view. Try your best to understand where they are coming from.
Keep track of your tasks. find your rhythm and habits, and be consistent. Document EVERYTHING.
Here’s one thing I believe in: you never truly know something until you can successfully teach it. Mentor or help others with their projects or even a simple task. Not only it’s a nice thing to do, but it will also improve your skills in the process.
