If you have to shoot two birds in the sky, what should you do? If you try to shoot both at the same time, you will shoot in the middle and miss both. The right answer is obvious: Shoot one by one.
But if you focus on one of them, won’t the other one fly away. It could. But thinking about both is not going to change that. Just let go, and do what is possible.
When you have a long to-do list, worrying about multiple tasks and switching between them is like shooting between the birds.
Don’t do that – shoot one by one.
