tattoo questions? how much writing is too much?

I'm sure that would be fine. But I would limit future writing to something that could either be done on your collar bones, or down your spine (probably collar bones, personally).

But I always prefer to try and avoid words and phrases, and instead use some form of symbolic imagery. Children's names are perfectly fine, for me, because you cannot predict how long any particular symbol will remain symbolic for them (even in your own mind).

I just personally find that imagery can be more personal than writing, in most cases (unless part of what you are trying to express is that you are "like an open book" since most word and phrase tattoos are very easy to comprehend). Images can also be much simpler, and more easily incorporate multiple meanings as opposed to just one, two, or maybe three that may be included in a phrase.

But then, I prefer combination images. To elaborate on an example I used in a previous answer: If one of your quotes was to express your "inner strength", one of them expressed your capacity for love and affection, and one of them expressed your love for Asian cultures: You could represent your "inner strength" with a tiger, your capacity for love and affection with hearts, and your love for Asian cultures with a yin-yang symbol. These images are easily combined by using two tigers to create the yin-yang, and replacing the dots with the hearts. This kind of imagery can be much simpler, and carry more meaning, than any combination of words/phrases, or any group of words and phrases. (But of course, it's just an example.)
