Today's work is a lot different to the world your father, mother or your grandparents grew up in. This can be a positive or negative thing, depending on your perspective on life.
One of the great benefits of today's world is the Internet. Like never before it has empowered people across the world, leading to success and wealth for millions of people. Perhaps the Holy Grail of the working world is the idea of working from home, and thanks to the Internet that is now more possible than ever before.
The problem with working from home, or starting the journey towards working from home, is that there are those individuals out there who know that most people would like to work from home. Simply put, they will exploit that desire to their own ends. It's very easy to get scammed unless you pay close attention to the details (that are often buried 6-foot under a mass of small print).
So where do you start? Well the first thing to do is get your priorities straight. It's all well and good having a brave and bold business plan, but you need to "aim high, shoot low" so to speak. Make sure that your idea will allow you to provide for the necessities of life, pay the bills, feed the family, and the like. If it can't, you'll need to spend some time figuring out a way to make it work for those basic requirements.
The next stage in the process is to get the right mentality. Regardless of the scale of your ambitions you should treat any "at home" venture as a business. It may sound simple, but if you go in viewing it as a hobby you're likely to miss a great many opportunities along the way.
If you have a set of marketable skills then you can easily (with some work) set up a profitable business from home selling your time and abilities; if you don't, that doesn't mean you can't succeed, but you will need to look elsewhere for a product, service or offering that aligns with your goals and aspirations. One great way of setting up a business from home is to align yourself with companies that offer commissions to sell their products. Some are not so lucrative, but most offer great rates and brilliant customer services that will allow you to fuel a growing and successful business.
However you need to be cautious. As the old adage goes: "if it seems too good to be true, it probably is." There are a wealth of shady businesses and individuals out there offering seemingly amazing ways for you to make a great deal of money, but almost invariably these are scams, or at the very least exaggerations, that could lead you to ruin. If you don't think a service is realistic in its claims, it probably isn't. That doesn't mean you shouldn't pursue such avenues, but pursue them with a great deal of scrutiny, and if in doubt walk away.
One good idea is all it takes to make a success of yourself by working at home. There are a wealth of famous quotations that emphasise this point, and they are never dishonest. Generally the difference between success and failure will fall on your effort and mentality. If you don't believe in yourself, or don't put in the hard work, you will probably fail. Believe in yourself and the product or service your are offering, and put in the hard work that is required and you can - and probably will - be a successful business person from the comfort of your own home.
