There is a tension between execution and challenge.
Execution is about getting things done. When you execute, you act on assumptions, hoping that those assumptions are correct. Assumptions come from experience and from socialization (the assumptions of others), and in most cases they help us get by.
Challenge is about changing things. That’s when assumptions get questioned, when you are seeking a different way, something new. Challenge is a more solitary job than execution, and it requires additional energy to buy people into your new perspective.
Balancing the two is necessary. If you only execute, things will not progress, you will not progress. If you only challenge, you will soon deplete all your energy, and eventually be left alone.
What are you going to settle for?
What are you going to fight for?
Be aware of the composition of these two buckets.
