text: Collaboration I think is the most important skill to have to know on this list. Not only will you have to know how to talk properly at work, you will also need to know how to talk properly anywhere you go. That is why the more you talk to people in a group the more you help your collaboration skills. Collaboration doesn't always have to be oral. It can be done when texting someone. Make sure you think before you speak also that is on where everyone has trouble on, even adults.
