One first good step is to get something decided about the tattoo you want to get. The better advice anyone can get, is not to get tattooed unless you know exactly what design you want. If you aren't 100% sure you want a specific tattoo, don't get it.
To make a good choice of your tattoo, you can start by narrowing your way, picking a tattoo style you would like to get. For example, you may like biomechanical and old school tattoos a lot, and besides these two, Japanese style tattoos as well. In this case you have already chosen a couple of tattoo styles you would like to get and left out many others that you wouldn't. Unless something makes you change your mind about this, you have a very important issue solved that will help you choose not only your next tattoo, but your next tattoo artist too.
Once you know what style you'd like, you can start browsing the Internet to look for tattoo artists/studios (preferably, an artist specialized in the style of your choice). The search of an artist through Internet is a little tricky so you have to keep your eyes wide open and pay close attention to what others say about the people you're investigating about. A good beginning is to google for a term like (in case you live in Toronto, for example) "tattoo artist(s) Toronto" or "tattoo studio Toronto". This will throw a list of tattoo artists/studios that reside near your location and it may even display a link to Google Maps, where you can get information about the roads and travel times.
