Every resource on time management and productivity discusses having the ability to say no. This assertiveness helps prevents distractions, saves personal energy, reduce stress, and reduces the risk of feeling overwhelmed. If saying no is a struggle for you, here are four other ways to do it: 1) Let others know in advance that you will be busy during a certain time or defined period. 2) Ask whether a certain task can be postponed. 3) Recommend another source of help or person with better capability, more desire, or the ability to produce the preferred outcome for your requestor. 4) Postpone your commitment to saying yes or no to a future date.
