Quoted from pookycade:It has pretty much been blind stupid luck.
You're not giving yourself hardly any credit at all. These people aren't coming in because it's raining out, you've obviously built an experience that attracts people. People want to have birthdays there. People like to return. People talk about it and attract new people.
You're making money in a business most people are unable to. Congrats on a job well done, no luck involved in my opinion.
