When I got my first tattoo, the tattoo artist handed me this little card and said "Here. This is how to take care of your heart."
I know that he meant my heart-shaped tattoo, but, if you think about it, I suppose that the directions could be applied to one's own heart. Follow them to the letter and all should be fine as you put your heart and yourself out there to be loved..
Most important: don't pick at it.
