You have lunch with a friend who was recently promoted to a management position. "Congratulations!" you say. But she looks at you and says, $"$I$\text{'}$m not so sure."

She goes on to tell you that she's overwhelmed with the pace of the work and the demands on her time. "I used to just think about myself and my own performance," she says, "and now I$\text{'}$m constantly dealing with all these interdependent aspects of the organization. I$\text{'}$m expected to motivate other people to work hard$-$just working hard myself was a lot easier. And the interruptions! I have to shift gears constantly."

She asks for your advice: "I would love to get more done in less time, be more relaxed, and have more time to enjoy my job and my life. Do you know any time management tips?"

Which of the following techniques should your friend use? Check all that apply.

Don't spend any time planning work$-$just do it$.$

Prioritize tasks according to what will take the least time.
