You Don’t Want To Be A Jack Of All Trades
You probably have already seen a bio like this one on Twitter, LinkedIn or on some other social networking site: John Doe is a web designer, programmer, SEO consultant, web entrepreneur, author, speaker, business coach, journalist and tech enthusiast. Not sure about you, but when I come across bios like the one above I immediately conclude two things: 1) the person is not really sure about what she wants to do professionally and 2) she is not going to achieve outstanding results on any of the mentioned fields. This concept applies to any aspect of our lives, and he is one offline example to illustrate it.
