I read about a new way of looking at imposter syndrome recently, which akins it to the brain's defence mechanism to new found success. The article by Ruth Gotian goes on to say that the feeling of being inadequate which accompanies imposter syndrome should be viewed as a celebration of success.
For long, imposter syndrome has been seen as a marker of anxiety and depression. While telling yourself that nobody is perfect is easier said than done, humans are social animals and are bound to compare themselves to others. This is more accentuated in corporate environments. Amidst this, removing the stigma associated with the syndrome by viewing it as a sign of success will surely help in avoiding self sabotage.
