Do More by Doing Less
Respecting your time also means setting achievable goals with your time. People can get excited by the idea of to-do lists and can end up creating lists with goals that are impossible to finish on time, and hence set themselves up for failure. Remember that to-do lists are useful only when the tasks listed can be completed in the time allotted.
Here are two simple strategies to stop over-committing your time.
Be realistic with your time plan. When creating to-do lists, be realistic with your time estimates. While it is tempting to add more items to your to-do lists, it is often smarter to select fewer work items that are really important and to complete them on time.
Learn to say no. Instead of saying "yes" to everything that comes your way, learn to say "no" for the tasks that you cannot complete within the time frame required. Your colleagues and employer will respect you more when they see you as a person who gives the utmost attention to completing work items on time and with high quality.
Keep in mind, though, that you will sometimes have to make exceptions to this rule.
