I feel burned out after finishing my master. Should I take year off before the PhD?
I would definitely advise taking a year off if you indeed feel as you've described. Burnouts are common and costly, and you might want to prevent one at all costs. There is nothing wrong with taking a break. Even though in academia it's sort of subliminally assumed that you're going to sacrifice your life, sanity and your unborn children to research, there really is nothing bad to say "hey, I need some time to myself." And no one is going to care, least of all admissions committees. You can even turn this break to your advantage by doing some volunteer work, or part-time research work. Seriously.

Personally, I spent 5 years doing undergrad in psych, then 2 years doing a Master's and by the time I finished my first year of PhD in clinical psychology I was so burned out after 8 years of post-secondary education and 5 years of constant academic research that I crashed &amp; burned and dropped out of the PhD. Periods of rest are conducive to general sanity. Best of luck.
