The summer is a perfect time to kick back and reexamine your LinkedIn profile.
Does it truly express what you want to convey, does it impress, does it say WHY YOU?
It may call for a total demolition and rebuild.
It may prod you to make small changes and tweaks.
Or it may require something in between.
Often when I work with my clients, I tell them not to go too aggressive in making dramatic, sweeping changes, but rather to change one section at a time, then move on the next section, all with the eye to make the sections cohesive and contribute on their own, and as a whole, to the same story.
Nip away at one section at a time and the task will not seem too daunting.
