Whenever you overload your day with so many things to do, you often end up multitasking to get through the day, and this could lead you to not putting enough time into caring for yourself.
Rushing through things can get the work done, but not properly, and this leads to an ineffective running of your business. It could even get embarrassing when customers and teammates begin to notice the drop in the quality of your work as a result of your rush.
So, pace yourself. Focus on the quality of the work you do rather than the quantity. It’s better to do one thing right, than a million things wrong.
