Sometimes project activities might make you stretch how you manage projects. You don’t compromise your ethics, but work within your personal constraints. You might not feel comfortable asking staff to work weekends, but sometimes you need to do that. You might not feel comfortable giving harsh feedback but sometimes it’s needed.
In the end you still need to like who you are ... you are the only one that has to be with yourself every second of every minute of every hour for the rest of your life. If you cannot like yourself, then it might be time to look for a new job.
