Am I burnt out or lazy?

since high school, i've been cycling between two phases: wow, this girl is productive, and wow, this girl can't get anything done. when i'm in a productive phase, working comes easily to me. and when i'm in an unproductive phase, it's the complete opposite. during these unproductive times, i take a step back and analyze what's happening. and what i'm trying to figure out is am i being lazy, or am i burnt out? so today, i want to talk about the difference between laziness and burnout because they are kind of hard to distinguish, but understanding where you’re at helps you get back on track.
