Overcoming impediments is not for the timid. It requires a single minded purpose, a completely uncompromising attitude, in order to overcome the obstacles that face your team. For the scrum master, it is the impediments that you face that will define your skill and ability as a team leader. Every impediment that you fail to address reduces your value to the team. Every impediment you are able to remove increases your value to the team. It’s really that simple. Remember that the next time you face a daunting impediment that blocks the team’s progress.
The only use of an obstacle is to be overcome. All that an obstacle does with brave men is, not to frighten them, but to challenge them.
– Woodrow Wilson
