In context of your projects, your life, your business:

Statistics and data offer an analytical view of your actions.  This is the black and white view.  Analysis is important since it provides a factual (not emotional) view of your efforts.

Critics by definition, judge both the merits and the faults of a work.  Approach criticism from your position of power: you are the creator, yet you are balanced enough to learn from someone else if there is something to learn.

“Doing it for you” is the most important aspect of these three.  This should be the core of every iteration.  When you choose to take on a new project, a new line of work, a new exercise – find your reason for doing it for you.  If you are assigned a certain task by your boss that you don’t want to do initially, reframe it in such a way that you can find the opportunity in it.  Make the project yours, take ownership of the reframed perspective so you see your benefit from it.

If you can successfully frame your work and life so that you are doing things for you, then you’ll see analysis and criticism as teachers leading you down the path of improvement.  This is satisfying.
