If you're able, think seriously about visiting someone who has been on your mind. A visit can encourage someone so much. I take part in the ministry of Gospelink (check it out -- it is great http://gospelink.org) and in one of their newsletters the writer talks about visiting a preacher in Africa. The preacher was so blessed because the writer came all that way just to see him.
A visit can encourage, help, bless. You can pray with the one you're visiting. You can just help him or her remember how important he or she is.
It's a simple thing to do but it has the potential to do great good.
