If you are a good homemaker and want to make use of your free time. Analyzing and investing in share market is the best way to learn the business and keep yourself updated. Initially start with a small amount of money and learn how to make money with intense knowledge.
My second idea about keeping yourself engaged is to start an online business like food blog, fashion blog and plantation blog. And write your views about your product. Then ask the online viewers to contact you by placing orders online. So that its easy to get the new buyers and deliver through online order.
Thinking potential and thinking positive is the best way to get real happiness.
