Shit happens. One can get sick, a pandemic can strike, or other parts of life get off balance.
It is tough to work and focus in such situations.
What does one do?
The first thing one can do is not beat yourself up for something over which you have no control, like the situation you are experiencing.
Next up, identify what is in your control. You can ask for help or hustle to get back to where you were. You may do the bare minimum. Just do the small stuff.
At this point momentum is more important than forward movement.
Once you see some momentum, start doing some hard things that move the needle in the business and then continue to build on the back of this small momentum.
With this you’ll be back in the game.
