It depends on the reason behind the tattoo. I have 3, small, black ones. One is a cat on my right wrist, because I love cats dearly and will always love them. On my left wrist is a tribal heart and it symbolizes my new found love for God. The last is on the right side of my neck, behind my ear. It is a dove with a halo that symbolizes my spiritual growth and love for God and Jesus Christ. I value each one and will never regret none of them because they represent things I love and will always love. I also drew them myself and had them put on. I will never put someone else's work permanently on my body.
If you simple get a tattoo without reason, you will end up regretting it. I know quite a few people that have gotten them and regretted them in the same year. To have something without meaning or purpose is pointless.
