If 150k will get you through six months and then some, take the time. If not, evaluate your spending and increase your savings so that you can take time off.

If you are taking time, expect that you will need or want a new income vessel when you come back, and that will take time to put in place. Few career paths will let you take any significant time away and just jump right back in where you left off.

Also, if you are burned out, start thinking of a clear exit plan.
