In the following sentence, should I use 'with' or 'for'?
Blood donation is a good way to share your love for others.
Blood donation is a good way to share your love with others.
Both are perfectly acceptable. To nit-pick, 'share your love FOR others' might suggest you are sharing with your fellow blood-donors a joint love for those who will eventually benefit. 'Share your love WITH others' might suggest you are sharing with the recipients of the blood. But these are just niggly little aspects...I would just use whichever appeals to you the more.
