On Target

In general, Rowan individuals are basically idealistic and progressive thinkers possessed of visionary minds, coupled with strong humanitarian and spiritual principles. They thrive on change, becoming impatient with convention or restriction. Artistic, original and unconventional, Rowan people can appear to others as detached and aloof for they are self-contained individuals and their vision is not necessarily always shared by the rest of humanity. Their cool temperament disguises many passionate beliefs and the need is always present for these individuals to argue their case against bigotry and ignorance. If Rowans are unable to find an outlet for their powerful imagination, they easily become restless and quarrelsome. Being true individuals who hate conformity, Rowans are natural born leaders but, because they often adopt unpopular causes, sometimes have very few followers. They are kind and thoughtful people but have problems in following others, which can lead to serious authority issues. Rowan people make for excellent listeners and are very respectful of others' opinions. Since they are somewhat unconventional characters in their approach to life, however, they have a tendency to be a little tactless and may alienate people. Rowans are also liable to antagonize through debate and escalate a situation out of proportion. In terms of a career, the Rowan individual is naturally drawn toward modern technology and possesses an overwhelming desire to reorganize and improve on anything which might be outdated. ... Those born between these two dates also fall under the lesser influence of a secondary tree...the Poplar, whose motto is "Overcome Doubt" or "The Uncertainty." Poplar individuals have a decorative appearance but tend lack self-confidence. They are prone to mature very quickly and assimilate things equally as quickly. Displaying courage only when absolutely necessary and hostile only toward extremists, the narrow-minded or hotheads, Poplar people prefer the goodwill of others and pleasant surroundings. This individual can be somewhat choosy, is often lonely and may harbor great animosity toward others. Artistic by nature, they are good organizers who lean toward philosophy. Reliable in almost any given situation, Poplar people cherish their friends and surround them with love. They take partnerships very seriously but are inclined to be generous only toward those who are generous in return. The life of a Poplar individual is made of judicious transactions and all manner of exchanges. If the Poplar perceives a warm and friendly atmosphere, then the heart and spirit opens...if not, then he or she will withdraw. Goblin Nation

This is by far the most accurate of any of the birthday based semi-religious tell-me-what-I'm-like things out there. I've always believed that religion and zodiac and all the other stuff of that ilk are basically ways to belong to a group. The bad stuff is on target at least. If you threw in a tendency to annoy people by taking their picture, you would have to put my photo on the description.
I found this on Goblin Nation. More specifically on the forum.
