Think you’ve had a rough day at the office? Here’s how one entrepreneur spent a really bad day:

8 a.m.: Come into the office before anyone else to wrestle over last month’s financials. Don’t trust the book-keeper.

9 a.m.: Morning management meeting. Spend most of the time doing all the talking, because who knows what will happen if you let them speak up?

10 a.m.: Cancel that order for new equipment. Efficiency costs too damn much.

11 a.m.: Interview a job candidate. Ask about their age, religious beliefs, and their interest in having children.

12 a.m.: Grab a quick bite to eat at your desk. There’s a chamber of commerce “meet and greet” over lunch, but things might fall apart if you leave the office.

1 p.m.: Ignore your newest employee as you pass his work station. You don’t want him to know you’ve forgotten his name.

2 p.m.: You just learned one of your team members has won a community service award. You say nothing, because what employees do on their own time has nothing to do with business.

3 p.m.: At marketing meeting, you announce you are cancelling the upcoming customer survey. In tough times, frills have to go.

4 p.m.: Hire the first person you interviewed. She seemed okay, and who has time to check references?

5 p.m.: Write a blogpost about the joys of running your own business.

6 p.m.: Head home for quality time with family.

8 p.m.: Pull out your laptop. Somehow, these financials are going to balance!

Most of them never had any training for the job; they owe their success to their personal knowledge of their markets and sound business instincts. But making it up as you go along only gets you so far.
