How to Choose What to Work On
You balance your personal needs against the needs of the team in choosing what aspect of a project to work on. You should do what you are best at, but try to find a way to stretch yourself not by taking on more work but by exercising a new skill. Leadership and communication skills are more important than technical skills. If you are very strong, take on the hardest or riskiest task, and do it as early as possible in the project to decrease risk.
