Do I expect you to become mouseless? No, but maybe you can learn to use the mouse less. The mouse is the perfect tool for some things, but often you can get something done faster using the keyboard. The next time the mouse falls of the desk into the wastebasket, leave it there and see how long you can work without it. Sure, there's a learning curve. For a given task you'll have to figure out how to use the keyboard instead, and then you'll have to remember those strange new tricks, but with repetition your new skills will become more natural and will provide a base for learning more keyboard tricks. It will take some work on your part, and of course not every task is appropriate for the keyboard, but keep at it; your patience will be rewarded.
