1. The batting cage idea is very risky. I’ve seen many of them close over the years and it is not anything close to passive income if you want to keep the business going. You have to continually promote it and target youth leagues, coaches, schools etc to catch all of the new players who grow up and want to play. I’ve played at probably 8 batting cages over the years and 7 of them closed.
Most earners__ salaried or businessmen__work hard to earn money for the family and the self. However, not all of these people, after they have earned money, also make their money work hard to generate some extra income. There are quite a few options which people could use to earn some extra income. Two of those routes are putting a small part of your hard earned money into Liquid Funds and/or accrual funds. Investing in these funds could also help retired people to earn some extra income. And if they are already getting pension, earnings from these funds could work as a source for a second income for them.

Inspired by you, I started a tax/personal finance a month ago. I figured if it works out, it will create a good side income for me. If not, at least I can use the blog to build my brand as a tax lawyer. Other than that, my current investment portfolio is heavily focused on index funds because of its historical performance and tax & cost efficiency. Right now my dividends income every year is about $14,000. I also have a good amount of unrealized capital gains every year from my investment, though I don’t count the capital gains as my passive income as they are paper gains, at least for now.

Excellent collection of ideas!!! As always, very nice write up. Also for people interested in teaching say you are good in some technology, you can go and drop your CV to any training institutes which teach that technology. Most of the training institutes these days do not have full time faculty working for them, its mainly people working for some companies coming and taking part time classes as a visiting faculty either during weekdays/weekends. You just need to go teach and get your pay which will be either in terms of per hour basis or per course basis. Very effective way, though I do not do it now, I had used this for quite some time and made some good money.
Even if each patron only contributes a very small amount each month, it can still be a huge source of income. Take a look at the Patreon page for Kinda Funny, an internet video company. They have over 6,209 patrons which means an average of just $3 a month would be a monthly income of almost $19,000 – plus they get cheerleaders that are always happy to spread the word on their brand.

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.
Portfolio income can come from multiple sources – interest/bond coupons, stock dividends, financial strategies including derivatives and capital growth.  Each offers some cash flow and some also offer potential capital gain with some risk from liquidity and volatile prices.  In this low-yield environment, many investors rely too heavily on cash flows and to pursue this are venturing further into riskier areas than they’d normally consider.
