Maybe you think they did. Maybe you think, "I paid my dues, I worked hard, I raised my kids right... Now I need a loan for a new business and...the @#$% banks won't give me one! That's just unfair!"
No one ever said it would be simple.
No one ever said you wouldn't have to make sacrifices.
However, I bet you have heard people say...
Get up and start again.
Don't give up.
If not today, when?
I could go on and on. The point is, running a small business is hard work. You must sacrifce. You must prepare for lean times. You must market, no matter what. You must be in "learning mode" continuously - do not for one minute think you have all the answers.
And, you must never, ever give up. If this is your passion, if your new business means as much to you as breathing (and it should else why do it?), you must treat it with respect and consideration. You must not allow others talk trash to you. You must not allow others to steal your thunder. You must not covet your neighbor's happiness.
Make your own happiness. Work is play. You are, indeed, in charge. Know that when the going gets tough, the tough get going. And, my personal favorite: Just do it.
