Do you like where you work, and does it pay enough for you to live comfortably? I think that's the most important question
Next is how long do you think it would take to get a new job if the contractor life isn't for you?
Other than that, I'd lean towards going for it. You can make a lot more money as a contractor or you can work a whole lot less. Finding work can be difficult, but if you make relationships work tends to lead to more work
Granted, finding work can be challenging and stressful sometimes, so it's not for everyone
Anyone who says that is pretty stupid, but I don't think I've ever met someone who actually held that position
I will say that working to colonize Mars will teach us to fix the Earth... But it would be real nice if we stopped fucking up the Earth in the first place
