If you can't pay for a thing don't buy it. If you can't get paid for it don't sell it. Do this and you will have calm and drowsy nights with all of the good business you have now and none of the bad. If you have time don't wait for time.
When you're surrounded by all these people it can be even lonelier than when you're by yourself. You can be in a huge crowd but if you don't feel like you can trust anybody or talk to anybody you feel like you're really alone.
