Normally you're not much of a joiner: if there's one sign in the zodiac who's most comfortable going it alone, it's you: but right now you make an exception for a truly worthy cause that needs your immediate attention and your formidable skills. You won't regret lending a hand, especially when you see how much your attention is appreciated, and how well it meshes with what others have to offer as well. Give 'til it hurts.
