The Year of the Dragon will be exhausting and brilliant. It’s a year of pageants and fetes, spectacular victories (or defeats)! This is the time to push your way to the front; be ambitious and enterprising. Significant events on a world-wide basis mark the beginning and ending of a Dragon year. It is a daring, flamboyant time, a year that brings with it the thrill of danger, of excitement, of the unexpected. Expansive gestures, ambitious schemes and lavish productions are the order of the day. Dragon years tend to favor the bold and pioneering; they are considered positive for enterprise and starting new businesses as it is always good luck and prosperity when the Dragon comes around. For example, the Chinese consider this a good year in which to get married and the most desired birth year for a child. The aspects are favorable for resounding successes, either militarily or in the political field. But here care must be taken as such victories are in general illusory and the inadvertent may also experience dramatic disasters.

The Year of the Dragon is considered to be an unpredictable time period. Because the dragon is such a huge, powerful beast, one cannot see its head and tail at the same time, indicating an element of mystery as to how events will develop in the upcoming year. The strength of the dragon empowers us with a large degree of luck, but whether the luck is good or bad will depend on the person. The choice to turn bad luck around to work in your favor, or to improve on the good luck you receive, will require great passion on your part.
On the political stage the Year of the Dragon will bring significant change. This is an election year in the United States and the campaign will be fiercely contested with dramatic swings in fortune. The United States will not be alone in seeing change, for this Dragon year will also bring significant transfers of power in other nations. Another feature of the year will be the vigorous campaigning by certain groups for causes in which they passionately believe. In some instances, the events that occur will have far-reaching effects, sometimes even crossing national borders.
Expect some lavish and often grandiose schemes to be announced this year, including major building projects and new attractions and cultural centers. There should be a buzz of excitement particularly in the arts and in the world of music, with new artists emerging to great acclaim with novel styles, sounds, and memorable performances. Sports followers can look forward to a great year with numerous records smashed as well as inspiring performances by both individual players and teams. Stock markets around the world will be prone to considerable swings of fortune during this time, and investors will need to keep their wits about them.
The influence of the Water Dragon in 2012 will increase the likelihood of success for progressive movements gaining strength around the globe. Energy conservation, green energy technologies, efforts toward reducing Global Warming, challenges to multinational corporations, endowments toward world hunger, and rejuvenation of the health of the oceans and sea organisms will all likely prosper. The negative side of the Water Dragon ascendancy will be a heightened forecast of weather extremes such as tsunamis, hurricanes, cyclones and monsoons throughout the year. However, of all the Dragon years the 2012 Water Dragon is most likely to bestow the legendary five Chinese blessings from heaven of health, longevity, love, wealth and a natural death at a ripe age.
