Introverts (or those of us with introverted tendencies) tend to recharge by spending time alone. They lose energy from being around people for long periods of time, particularly large crowds.
Extroverts, on the other hand, gain energy from other people. Extroverts actually find their energy is sapped when they spend too much time alone. They recharge by being social.
Ambiverts exhibit both extroverted and introverted tendencies. This means that they generally enjoy being around people, but after a long time this will start to drain them.
Similarly, they enjoy solitude and quiet, but not for too long. Ambiverts recharge their energy levels with a mixture of social interaction and alone time.”
