-A crucial thing in making software easy to use, is being mindful of [cognitive load](https://en.wikipedia.org/wiki/Cognitive_load) which dictates that *"humans are generally able to hold only seven +/-  two units of information in short-term memory."* This short-term memory limit is perhaps the most important factor in helping a user feel comfortable instead of overwhelmed.
