Many people are uncomfortable with bragging on their resume, understandably so, but it's important to distinguish between bragging and stating the facts.
Boasting in your summary about being a dynamic, innovative, results-oriented, and highly respected thought leader without a shred of proof to back it up is bragging (or making stuff up).
Stating that you turned around a severely underperforming, bottom-ranked store and drove it to top company rankings isn't bragging - it's simply stating a fact (assuming it's true).
Focus on the facts and leave the hyperbole for your competitors.
Best of luck!
