If there is work to be done, and you have time time to do it, do the work. Get it done when you know you can.
There may be something you want to do at the same time and yes, you’ll need to weigh the cost of skipping that to getting the work done. Sometimes those decisions are easy, sometimes they are not. But favor doing the work first. It has many benefits over the option.
In doing the work, you remove an obstacle from your path. You have control. You clear the way for things you want or have to do. If you delay the work, the work has control, especially if you’re up against a deadline. Don’t wait on the deadline for the work. Be proactive. Attack the work. Then you’re in control, and you’re working in the present.
You’re gifting yourself the future by removing something that has to be done and you get to use the future for what you want to do.
