Articles, books, presentations, etc.
If you are a successful writer or speaker, share that. If the topic is germane, share titles or topics. Alternatively, if it relates to a particular job list it under Experience.
If you put anything here, select stuff that improves your profile. Knowing what the recipient’s interest are, can guide what you might wish to include. Avoid dangerous stuff like skydiving and lava surfing.
Include volunteer activity that relates to the job and the company. If community involvement is valued by the company, relate to that. Volunteering fits especially well for a not-for-profit job.
When choosing what to include think two
hours per year manning the church rummage sale, probably won’t help. Chairing
the rummage sale for 5 years and raising $25,000 might be worth including.
