Be in the Zone

"Be in the Zone" is an autonomous interaction gained when a Sim reaches the final level of any hobby. Being "in the zone" causes the Sim to glow with a white light whenever performing an action pertaining to the hobby they have reached the maximum level in. However, it appears that Sims cannot be "in the zone" while in areas where enthusiasm cannot be built.

All hobbies

 * Sim glows with a white light.
 * Sim gains skill points faster.
 * Needs decrease slower when in the zone.
 * Sim completes random action/build/make faster when using an object that puts them in the zone i.e.: using the Robot Crafting Station with maxed Tinkering Hobby.

Music and Dance

 * When playing musical instruments or using the ballet barre, Sim appears to be in a spotlight.
 * When playing the piano or violin, Sim changes into Formal outfit, and an invisible audience claps.
 * When using the ballet barre, Sim will hear piano music and an audience clapping.
 * Sim gets paid more when playing for tips.

Film and Literature

 * When reading books from a bookshelf, a tune relating to the book's genre plays (e.g. a bouncy, happy, childish song that would suit a kid's show plays whenever the Sim reads a children's book).

Sports

 * When playing basketball, an invisible audience begins cheering.

Tinkering

 * When operating the model train set, the sound of a real train can be heard.
 * When working on the One Man's Junk Car, the sounds of a muscle car's engine can be heard.

Glitches and errors
Быть в «зоне»
 * There is a glitch in the game when Bigfoot reaches maximum enthusiasm in any hobby. Sometimes, the game will say that an error is happening with Bigfoot. If the player chooses to ignore it, the Bigfoot will still be "in the zone" and glow with a white light, but will not receive any effects of being in the zone.
