There is ALWAYS More To Do and You Always Feel Like You COULD Be Doing More

Regardless of how much you do, there will always be more that you could be doing. That doesn't mean you aren't doing enough.

So, if the list of things you could be doing seems long and intimidating, celebrate. You are on the right track. 

And whatever you do, do not try to do all of those things. 

View it as a list of things you could possibly do in the future (or not) and then let those things go for now.
