It all depends....
Is what you've always wanted to do is sit on the ground and play in mud? Because in the world today, you can't live off that... There's better things out there than 38/year.... I'm not sure where you live, but my mother makes 36k/year we're right on the edge of living in poverty... And poverty and middle class isn't separated by only 2 grand... Granted, you'd only be living for yourself (as far as I know, maybe you have a wife and 10 kids, but for the sake of the rest of this message, let's say you're solo) so 38k/year would probably be amazing for just you than compared to raising 2 kids alone on it... I don't really know that perspective of it.
But, money also doesn't matter... if you can get by, even if it's JUST BARELY by doing what you want... Then do what you want, be happy, live life the way you want to... But, if it'd be impossible to pay bills and etc by doing what you want... I'd suggest against it, but in the end, no ones opinion matters. The only thing that matters is how you see it, how you look at it...
For all I know, maybe 38k/year makes you even happier than doing whatever it is you want... Maybe your the type of person who is made happier by money than by petty dreams... I'm not saying that'd make you bad, or a dreamer bad either... But the answer to your question all depends on the type of person you are....
