Introverts risk burnout from trying to do too much, trying too hard and trying to be all things to all people. Learn to deal with burnoutit happens by learning your limitations and sticking to them, dealing with any emotional issues that you've ignored (therapy, writing, meditating, etc. are good ways to do this) and knowing what can trigger problems for you (such as too little sleep, worrying too much, negative comments, etc.) and finding ways to nip each trigger in the bud.
