I’m not sure why you brought up the things you did. Your son in college has nothing to do with your present situation. Your dad passing shouldn’t mean anything in your success and survival. Your child at home is your singular issue. 4 years unemployed is impossible unless you’re living on an island. You worked your entire life? That’s like 20 years or so only, you quite possibly have another 40+ years left. You’re the one who is going to have to decide that the excuses are over and you need to either apply to jobs or start a business. Or enjoy the time with your child at home while on public assistance. But stay sharp and be ready! YOU ARE AN AMAZING WOMAN WHO IS CAPABLE OF ANYTHING YOU PUT YOUR MIND TO!

Considering that you have a finite amount of time, passive income should make up a large part of your work. If you're serious about generating any semblance of income online, then passive income should be one of your sole goals and ambitions. Why? Wouldn't you prefer to do the work one time and get paid repeatedly as opposed to relying on your time to generate that income? Invest the time at the front-end so that you can reap the benefits on the back-end. This means putting in a bit of sweat equity and not getting paid today. Rather, you'll get paid somewhere down the road. And you'll continue getting paid whether you keep building that passive income stream or you stop.

But if you do go the fashion route, be prepared to do quite a bit of networking before you get your business off the ground. Don’t be afraid to do free consultations for contests and giveaways. The more word gets around about your fabulous fashion sense, the larger a clientele you’ll build. If you’re really good, you can start this business with little to no training.
If you own the business entirely by yourself and plan to be responsible for all debts and obligations, you can register for a sole proprietorship. Be warned that this route can directly affect your personal credit. Alternatively, a partnership, as its name implies, means that two or more people are held personally liable as business owners. You don't have to go it alone if you can find a business partner with complementary skills to your own. It's usually a good idea to add someone into the mix to help your business flourish.
