Yes i understand you. That is why, my sketch for my future tattoo waited for 2 years before i said - ok, this is it! Tattoo is something u will wear for your whole life, so it must be something that really describes you, or means really much to you.
Yes, mine is a symbol. Not to big, not to little, just right. I will put it on my back, under the end of my neck. No colours, only black. And i will do it after this summer... cant wait!
Take photo of your naked body, from front and from back, and then in some program like photoshop, stick it on you and see how it would look. That works good.
