On Linkedin I see all the time people who have one or a mix of titles like:
1. Guru
2. Creative thinker
3. Visionary
4. Evangelist
5. Mentor
6. Strategist
7. Generalist

Anyone who refers to himself (primarily men) using such titles seems to be in a need of shrink's help. These titles are symptoms of narcissism and inferiority complex.
