It’s easy to focus on yourself and your job. After all, you live in your own head all day every day. You don’t have a direct window into the motivations, drives, and actions of others. All you can do is go by the clues that they give you.
Trust is a hard trait to foster. It’s easier to remember the times that you’ve been burned by others than the times they picked you up. Over time, those negative occurrences continue to add up making it even more difficult to trust. There’s a reason that people are generally more jaded as they get older.
Teams can always accomplish more than individuals. Even the biggest individual accomplishments in history owe some of their success to teams. It’s really difficult to train completely in isolation. New ideas usually need someone to bounce them off of. New products take a team to build even if the conception happened separately.
Foster your teams. Make sure you participate and help pick everyone else up.
