First of all, let's face the facts. Working 9 to 6, you won't have any time during the day. If you choose to have a second job during the evening hours, you'd get burnt out very easily. Chances are that you might under-perform in both the jobs. I recommend having a side business rather than a second job. Some investment of money and time would be required at first. I have come up with a few options that would require less work from you but would be a decent second source of income.
Perhaps a coworker purposefully tries to make your life miserable because they resent your success. Maybe you get passed over for a promotion and a raise because you weren’t vocal enough about your abilities, and mistakenly thought you worked in a meritocracy. Or maybe you have a new boss who decides to clean house and hire her own people. Whatever the case may be, you will eventually tire.
The business process outsourcing services in the outsourcing industry in India caters mainly to Western operations of multinational corporations. As of 2012, around 2.8 million people work in the outsourcing sector.[216] Annual revenues are around $11 billion,[216] around 1% of GDP. Around 2.5 million people graduate in India every year. Wages are rising by 10–15 percent as a result of skill shortages.[216]
India's infrastructure and transport sector contributes about 5% of its GDP. India has a road network of over 5,472,144 kilometres (3,400,233 mi) as of 31 March 2015, the third-largest road network in the world behind United States and China. At 1.66 km of roads per square kilometre of land (2.68 miles per square mile), the quantitative density of India's road network is higher than that of Japan (0.91) and the United States (0.67), and far higher than that of China (0.46), Brazil (0.18) or Russia (0.08).[234] Qualitatively, India's roads are a mix of modern highways and narrow, unpaved roads, and are being improved.[235] As of 31 March 2015, 61.05% of Indian roads were paved.[234] India has the lowest kilometre-lane road density per 100,000 people among G-27 countries, leading to traffic congestion. It is upgrading its infrastructure. As of May 2014, India had completed over 22,600 kilometres (14,000 mi) of 4- or 6-lane highways, connecting most of its major manufacturing, commercial and cultural centres.[236] India's road infrastructure carries 60% of freight and 87% of passenger traffic.[237]
For a person working for a wage, their source of income is their job, or their labor (aka their time that they sell to someone). But you can own a house, and rent it out, and when your renters pay you renter every month, the source of that income check is your rental property, or your house. It would just be called rental income. If you have money in the bank in an account that pays interest, those interest payments are another source of income. We can say the source is interest payments, or we can identify the asset that is generating rent, and say your money in the bank that is generating “rent” (aka interest) is your source of income.
