Stop Procrastinating
If you're a procrastinator and have important tasks coming up that can't be put off – try thinking about the task before you sleep. It will force your brain to act on them mentally and your brain will start to draw a pathway to the completion of the task. Simply put – before doing a task in the physical world, do it in your head first. When you get to it in your real life, the brain will have already processed a huge chunk of the task, making it easier for you to actually finish it.
I have successfully procrastinated by doing exactly this, as the more I think about it, the less actually do it!
