Oh, I’ve so been there. I have done the hours, had knocks in business and felt OMG this is hard!
We are humans at the end of the day, and we can only resist negativity for so long.
If you feel like your getting tired, your more negative than you usually are and you are focusing on what isn’t right, it means your burning out.
Burn out is bad, but the great news is that it can be avoided.
My advice for when you feel burnout coming?
I love going to bed early that night (if possible) and unplugging from work (once one can). Sometimes you may be busy and can’t avoid that, but once the critical stuff is done, I rest up. Then the next day, you’re usually fine.
Rest up and remember friends; business is a marathon not a sprint!
