How to be a gojillionaire...like Vera Wang

So, I got a job the other day.  Not exactly what I wanted to do, but one must weigh the pros and cons and make a decision.  I decided, for the time being, at least, that the pros of getting a job outweigh the cons.  But it was close!
Don't worry, though, it isn't some awful 9-5.  It is piecework alterations three days a week.  No biggie.  It will mean a regular paycheck.  And it doesn't mean that I stop doing my own thing, not at all.
Anyway, during the interview,after seeing my portfolio pictures, the owner of the shop asked me why I don't open my own shop.  I have been asked that several times, actually. So, here is the answer.
Right now, I don't want to. 
Before I had The Small One, I worked a lot.  I worked at Brigham Young University full time and also did custom gowns on the side.  After I left my job to care for my (much adored) nephew, I still needed an income, so I kept doing custom gowns and even advertised.  I got very busy, but was still able to care for my nephew as he was a very sweet and easy baby.
When nephew was 3, I had a baby of my own.  She was not a sweet and easy baby.  She had colic to begin with, which made working hard.  She is/was an infinitely more demanding than little nephew.  Different personalites, you know?
So, I dialed back the work load to care for the baby.
Well, when she was 1.5, I think, the business with which TMOTH was affiliated went belly up.  We lost, big time.  So, I went back to work at a bridal salon as a designer/alterations manager.  That lasted for a while, but didn't end up working out.  The Small One did not deal well with me working full time.  So, I left and went back to doing alterations and custom gowns out of my own space.
Fast forward to now.  We have some things we want to do which require money (like pay off debt, for one.  Go to the UK for another), so I have decided to get a job with a regular paycheck.
TMOTH was not thrilled about the idea, he thinks I am shortchanging myself.  So do a lot of other people, for that matter.
But, here is the thing.
Running a business is HARD.  Really hard.  And you have to work more than full time to be successful.  Why?  Because, not only are you working full time at the actual JOB part, but you have to work a lot outside of the job marketing, finding work, doing paperwork, hoping you are figuring your taxes out correctly, worrying about whether it is worth it to have employees, etc, etc, etc.
So, I weight the pros and cons.
I could be successful at a bridal salon of my own, I think.  I am good at what I do.  I have a pretty good eye for design, I am a really good manager. 
But.  I also like my kid.  (Not to imply that other people who work don't like their kids, I know they do).
What it boils down to is this. 
I can make more money, but not see my daughter very much. 
Or, I can deal with being poor, and hate it, but get to be with my daughter like I want to.
I could have my own salon and not much time.
Or, I can work for someone else, let them deal with the business stuff, make a bit of money and be home with The Small One like I want to be.
For now, anyway.  Things will definitely change when she is in school all day.  I won't have her with me, anyway, so I may as well put in some effort towards a business of my own, right?
