Starting is often the most challenging aspect of task execution — you just feel
tired and can't even tell why. One of the best ways to escape this is by tricking yourself into starting, and a timer is an excellent tool for this purpose. How does this work? Tell yourself you're going to do whatever task you have for only 10 minutes.
Set your timer for 10 minutes and start the task. Do nothing else within this time except what you've set out to do. Stop once the timer rings, and then you can take a little break. Rinse and repeat, increasing the duration each time. You can use a cell phone timer, an egg timer, a digital watch timer, or whatever's available.
