Hmm...
Tbh, thats not an easy question to answer.
If it's something you really have a passion for, then certainly. Look into it.
But, if at all possible, try to devise a good plan where you have a reliable fall-back.
It's useful in many ways because, even if you succeed, things might not take off right away, and that safety net is useful.
Also, if things go badly, you still have a reliable source of income so you can always regroup and try again.
My Dad and I actually discuss this a lot. He's a strong advocator of following your dreams. Lol, he has this saying: " If you love what you do, and enjoy your work-- you'll never have to work another day in your life"
...or something like that.
Anyways, go for it man! You're much more likely to succeed in a career you love.
I'm not sure if you're still in school or not, but I'm sure your Guidance counslers will be happy to help and give advice.
Oh, and don't be afraid to fail!
