Get a tattoo

I want to get a tatoo of something. My idea is to get a new tatoo every 5-10 years, and have it represent what was most important to me in the past years. For example, the last few years I have been most interested in Japan-anime, the language, culture, going to college there-all that. Also, all I’ve done has been focused on getting into a good college. I think I might get the kanji for “growth” or “change”. Something that relates to both of them.
