In addition, read some and try to become aware of what others need and what others are working on.
Finally, when you become aware of problems or ideas, write them down. I'm a fan of small notebooks; other people use phones or computers or whatever. Look over whatever notes you've taken once a month, and once a year; look for patterns in those.
