Don't forget that many slightly older and wiser people, such as any interviewer you may encounter, regard tattoos as an alternative to a Post-it on your forehead saying "I'm stupid".
They are often not wrong, although such an attitude is of course totally unjustified, discriminatory, whatever else you wish to call it.
By the way, substituting "of" for have" is bad enough in spoken English, and worse in written English. There are many older and wiser people, quite possibly the same people as mentioned above, who would see it, quite unfairly if that is what you were taught, as another stupidity indicator.
