No way, it's not wrong. Everyone changes and the reasons vary, but even if it's as simple as 'I'm not into it anymore', it's still valid. In corporate vocations (using that as the example because that's all I have experience with), you have a lot of opportunities to move around and even if it's within the same company, people are experiencing different challenges, developing different skills, having different experiences. Idk that you can do that as well in tattooing, and maybe you just wanna do something else, even if it's just a break.
