Are you getting feedback on your own perceptions?
We see things differently, day to day. We might even distort what we're looking at. When we distort our mission or our goals it leads us astray. When we distort our performance ("I'm doing great! Sure I am! Everything is wonderful!") we risk falling off track. Things can get sketchy.
When you look in the mirror, remember that mirrors reverse everything. What you see is not what you see. Similarly, when you look at yourself, could you be revering things? Could you be getting it just a bit backwards?
Get feedback from others. Creatively check other perspectives.
Because our mirror lies, and we need help seeing ourselves.
