Should i do this tattoo or it will be the biggest mistake of my life ?
biggest mistake of your life. imo.
What snoopys says about searching a job is true. If you are really wanting to have one, make sure it is not visible when wearing summer clothing (t-shirt and shorts), this will make applying to jobs a lot easier.
Myself I have bling bling in my ears, but these are easily removed. Only the (very little) scars of the holes for it are visible.. but after time that will become less visible.
