How Do You Show You are Good: A Primer in Gentle Self-Promotion

For those who hate to self-promote (rule #3), work into conversation, or at least into your resume:

You work with top clients. It is understood no employer would assign you top accounts unless you have the necessary skills and judgment.
You negotiate or litigate against top companies. This experience shows you have worked on complex matters and against wily opponents.
You have good judgment. Do clients or colleagues request you again and again? Do you advise executives? Do you service top clients? Are you asked to go on pitches? Are you repeatedly asked to trial? Only those who provide good counsel get these types of experience.
You have good people skills. Advising the GC, C-suite execs, or senior leaders across different teams automatically qualifies you as someone who can speak truth to power.
You have numbers backing up your success. Statistics show that you have saved your clients $X or increased Y% productivity. Awards won and high ranking of performance all objectively show you are good. Numbers can also establish your ability to deal with high volume or high stress, e.g., listing your docket or size of deals.

Remember: items 1-5 immediately set you apart. Identify and then articulate them. No bragging required.
