Low risk,high yeild. Time Investment-time is money, but only if you use it well. You want a business that'll make the most of the time you have available. An hour spent is an hour lost, but an hour invested pays off again and again. You want residual income, and that means building a business that never losses momentum.
Some businesses are trends, they max out, and disappear.
You need something better, something that expands in all directions, an opportunity that grows in any economy. When your business depends on a single market, it collapses when that market does. You want a permanent business, one that's free to grow into every market available, a business that can adapt to any market. You don't want to do it alone. Small business startups are the riskiest investments, and that's a risk you don't need to take.
