Eat That Frog!.
And forget about solving your time management problems by becoming more productive. No matter how many personal productivity techniques you master, there will always be more to do than you can ever accomplish in the time you have available to you, no matter how much it is.
When I started ‘collecting’ things I needed to do on my ToDo list, I became discouraged because the list kept getting longer & longer even though I was checking things off the list.
That is why lists are important. You must have some way to prioritize what needs to be done because you will never get it all done. And, if you are not going to get it all done, it is best to do those things that are most important to you and let the others slide.
