Astro.com tells me this about my solar return:
Happy birthday! Today the Sun returns to the position it was in when you were born. As would seem appropriate with this transit, today is a day of new beginnings, and the influences you feel today will affect the entire year to come. However, this does not mean that the whole year will be disappointing if today doesn’t work out exactly as planned. You are receiving a new impulse from the energy center within you, as symbolized by the Sun. Therefore any new venture that you start at this time will ride the crest of this new energy and will very likely come to an acceptable conclusion. Whatever you do or begin today will bear the stamp of your individuality more than anything else. This is the day to assert yourself anew.
Beats the current Neptune square Mercury which represents fuzzy thinking. And I thought that was just hormones. 😉
