Share 'What's keeping you awake at night in your job or business?'

I admit it...I toss and turn and sometimes wake up panicked or thinking about something related to my business. I forgot to return an important call or email. I need to bother a client again to collect a late payment. I wonder if I calculated an estimate right. There are many others. I'd like to here what keeps you awake at night and for everyone to weigh in and maybe provide some help as to how…
