Hyperfocus is when we fall into an intense and deep flow state. When we're hyperfocused, we lose track of time. We forget to eat or drink water. We also usually get superhuman amounts of things accomplished. Hyperfocus is a state of mind, and is limited in scope to a single session.
Hyperfixation is a longer term phenomenon. It involves obsessive and intrusive thoughts about a thing, and repetitive hyperfocused sessions. It's usually accompanied by intense feelings of joy and excitement. It can last days, weeks, even months.
Hyperfixation is not all rainbows and unicorns, though. Which is what I'm struggling with, and what I'm writing about.
Does this resonate with you? Do you experience these things?
