It’s obvious, but every successful product solves a problem or fills a need- if the problem must be solved quickly, even better. What’s an urgent need? How about a car repair when you’re stuck on the side of the road (‘had the transmission on my car give out on a highway exit ramp. I don’t recommend it). Another good example is heat or air conditioning repair at home.
Finally, make sure you can service multiple types of clients. This is the best egg to have. Even for something as simple as a dog walking business, you can service multiple types of clients. For example, you can offer a puppy walking service and an adult walking service. You can have weekends at the park services. You can offer to take the dog to the groomers. Try to meet client’s individual needs.
You are also free to choose a fund that is based on any index that you want. For example, there are index funds set up for just about every market sector there is — energy, precious metals, banking, emerging markets — you name it. All you have to do is decide that you want to participate, then contribute money and sit back and relax. Your stock portfolio will then be on automatic pilot.
Article writing is one of those things that isn’t at all glamorous, and few people will get excited about it.  With that said, it’s one of the easiest ways to set up your passive income stream.  To give you some perspective, I wrote about 120 articles late last year and have hardly written any since then.  Since that time, my articles have earned me over $700.   I continue to earn $70-90/month without having to do any additional work, which is something I look forward to every month.

Or, there is another theory for your primary salary – generate enough to have a little excess cash flow, but do it at a place that you can work stress free and have time to dabble in other projects.  A good friend of mine has this setup – he works 10-5 and makes $50,000 a year.  This allows him to easily cover all of his expenses, but the shorter hours and flexibility in his job allows him to pursue his secondary income generating ideas!

I invest about 5% of my pre tax income in 401k that my employer matches. Have close to 70k in cash in checking. Also,I liquidated around 40k in my 401k and not sure where to invest that in (bonds vs stocks) because of stocks trading at record high. Have a rental property that is paying itself now and I will pay off the mortgage completely in 5 years. My immediate concern is the cash in checking acct that’s not doing much. Thanks for your reply and appreciate your work. I am learning a lot
In focusing on your wealth management goals, investment income is obviously critical but you might fund your goals from wider sources of income.  A typical long-term portfolio might produce about half its return as income and the other half as capital growth, though in times of duress the capital growth component wanes.  In this low-interest rate climate, some sources of income have become quite expensive and may prove disappointing against your spending needs.  But by tax efficiently and sustainably drawing income from wider sources, you might meet your goals while more prudently balancing risk against reward.
