It is relatively hard to become a tattoo artist. Even if you have natural drawing ability, it does not automatically mean you will be good at tattooing.
Tattoo artists often have to work for free initially to build a good portfolio of work. If you can get a paid apprenticeship from the start, consider yourself lucky.
Tattoo artists also have to make a big financial investment in the equipment needed to perform tattoo work. Becoming a successful tattoo artist is even more difficult. First, you need to build an impressive portfolio of your tattoo art.
You need to be able to stay extremely focused for hours on end while tattooing, as mistakes in this profession are permanent, unfortunately.
Then get a job at a popular tattoo studio. These jobs are actually quite competitive and hard to obtain. It typically takes years of dedication and hard work for a tattoo artist to become successful.
Many tattoo artists also experience a lot of physical issues with back, neck, and arm pains, from constantly bending over and using their arm to tattoo.
