An overwhelmed brain will not work well. You have to slow down and think about what is the most important thing that you can do that will make tomorrow better. Do that. Only that.
Delegate the other work to your people. Don’t have people? Get some. Can’t afford people? Then raise your prices. Can’t raise your prices? Add more value to your product or be a better marketer or salesperson so you can.
One thing at a time. Keep your brain working well.
