In my opinion, people have to be very sure of what they are doing when they get a tattoo, especially when they do it in a place which is usually seen by others, such as the arms and even the legs.
Firstly, we have to be very sure of what you are tattooing because something that really likes you now, may not like you in twenty years. That’s why you should be mature enough to decide to get a tattoo because this thing will be with you the rest of your life, so it will become a part of yourself.
In addition, people usually judge others by their physical appearance, including tattoos. Depending on the thing that you want to tattoo, you can show an ideology which people wouldn’t know of you without seeing the tattoo. That's why it is recommendable not to tattoo some sort of images which can be related to a political opinion or something like that.
To sum up, you must be very careful with what you are tattooing, especially if you do it in a visible part your body because other people could make a wrong opinion of you, which can have consequences both in your personal and professional life.
