Go on... sell yourself.
I hope you ended up reading this not because the title evoked a malicious feeling but because you indeed want to sell yourself... in a proper marketing way.
Everyday you see people market themselves as "Experts" and "Pros" and sadly most of the time others fall for the self-appointed title. But in reality, who authorized you to wear it? Your way of acting? Or is it the way you dress? No, the answer is simple: others.
If you carry any of these titles, tell me three things:
1. Are you an expert because you know how to read industry reports or conquer talking in front of others?
2. Is your Pro side going to help me understand more of what I need or help you increase your bill?
3. Or are you because others truly believe you are?
"Pro", "Expert", "Guru".
Simple words that don't carry a meaning when we find them in your Twitter bio or LinkedIn profile. However, their merit is established when others affix them to a description of who you are, for example, in a newspaper editorial.
"A man who is at the top is a man who has the habit of getting to the bottom."— Joseph E. Rogers
Remember that people like ME are the ones that allow YOU to wear a title. If you don't care about the true meaning of humility in business, go on, sell yourself.
