Keep an eye on which tasks are high priority and which are not. Too many times, we treat every task as if it's on fire. That is a dangerous way to think, is certainly not productive, and could lead to burn out.
So take a gook look at your tasks. Give each project a weight. Remember, they are not all weighted the same. Some will be less complex. That doesn't mean they are less important, only that they are less complex. Maybe your timeline for these is shorter than your timeline for the more challenging projects.
Then work out the start date and create deadlines for all your tasks. You'll start to see where the lower priority tasks fall.
Remember, everything is not on fire. And most of all, breathe.
