If you have extra time with you over weekends or after your job, you can freelance and take small projects. There are many websites like elance.com , odesk.com or freelancer.com where you can earn money by working on projects. There are thousands of people in India who are working full time on these kind of freelancing websites and believe me, they are earning in lakhs. Look at it as a serious way of making money and not just a time pass activity.
Freelancing is short term project you need to take from someone and complete it in pre-decided time. Once a project is completed you will be paid and there is no further term with the company. There are many websites where people post projects. Many people are working as freelancer full time. Websites like WorknHire or Freelancer are great places to start.
I like the way you have listed the ways to earn extra income and was quite surprise that you did not make mention of network marketing, which is a way to make extra income without quitting your regular, though most people view mlm as a pyramid scheme but the real pyramid scheme is a regular 9 to 5, because you can only have one president of a company at any given time and network marketing business model to promote product that can be used is really cheap to join and can offer a substantial extra income or what do you think?
Connecting two entities is another great way to make extra money by spending less energy. So can always have an agreement with some business entity to give clients on referral basis and earn a commission. I recently hired a designer for some work and I asked him if he knows someone who can PRINT the designs for me. He referred me to his friend who done the printing work. I am sure he must have got some cut for the referral and there is nothing wrong in it. Its a smart way of earning money.
Let’s say a company earns $1 a share and pays out 75 cents in the form of a dividend. That’s a 75% dividend payout ratio. Let’s say the next year the company earns $2 a share and pays out $1 in the form of dividends. Although the dividend payout ratio declines to 50%, due the company wanting to spend more CAPEX on expansion, at least the absolute dividend amount increases.
There is no doubt that our grievances against the British Empire had a sound basis. As the painstaking statistical work of the Cambridge historian Angus Maddison has shown, India's share of world income collapsed from 22.6% in 1700, almost equal to Europe's share of 23.3% at that time, to as low as 3.8% in 1952. Indeed, at the beginning of the 20th century, "the brightest jewel in the British Crown" was the poorest country in the world in terms of per capita income.
