What if I want to become a tattoo artist even though I've spent the last four years studying politics?
Why exactly do you want to become a tattoo artist?
I love art and the feeling of making an idea into reality
If you really love art that much then I think it's good for you to enter that profession. If you miss out on your dream job you'll end up with regrets.
I'm not so sure. Politics is more likely to lead me to a more successful career.
You could always explore tattooing as a hobby while you continue in politics, until you're more certain of which path would be best for you.
