"Process and schedules are mere tools for organizing people, don’t let them dominate you, the team, or the product. The best PMs are really good with people and care about the team’s success more so than their own because they know that a product and team’s success will ultimately be good for their own career. The role often puts you in a leadership position with the team—don’t be afraid to lead."
