The more I see people start small business, the more I see they think they are entitled. They deserve everything because they worked hard in the past, now they get to relax. Running a business is quite the opposite of a relaxing time and the sooner you realize that, the easier it will be.
Back to the entitlement thing though, people expect big things without big effort. It's about time people humble themselves and recognize those who are successful at what their doing. I'd say 99% of the time they had to work their butts off to get where they are today. And most of them probably had a few failures along the way. Fail happens, it's what you do with it after that makes the difference.
I'm not here to say that you shouldn't dream big and know in your head that you'll become successful, just remember it involves a lot of work and probably a few failures along the way.
