Are you a saver?

I am an introvert. I love my job, but after giving and giving all day in the classroom, at meetings, or in lab interactions, I need time at home to recharge, regroup, and basically become (semi)human again.

In order to be a semi-decent person in my home life, I have to save a bit of myself. I try to save my "best self" for my time at home, but I'm not always successful.

I'm not sure what extroverts do. Are they only recharging around other people? What is their home life like? Are they able to recharge with their significant others, or are extroverts miserable until they are reunited with a bigger group?

Do you save your best for your home life or do you use it all up at work?
