- Rich Dad, Poor Dad got me into the idea of 'passive' income. Nothing is truly passive of course, but it makes me think about what I do
- SourceGuardian. This is encryption software I set up in 2002 as I had a need myself and the nearest product was $6000 at the time. It has generated a great passive income since then. Enough to pay all my bills. 2016 was no different. I work with 2 other people on it, one of whom I've never met (he's in Russia) and it works well
- Competitor Monitor. This used to be a side-project 5 years ago, but it has grown significantly and in the past year we are up by 35% and we have grown our team. Strangely this has now become passive in the sense that I have created a structure and systemised the business (read The Emyth Revisited book) and that has allowed me to step out. I am not more of an investor than a day-to-day contributor
- UKscrap.com. This one died in 2016. The site is still there, but competition and my lack of interest killed it
As I said, nothing is truly passive, but you need to have a passion for whatever you do and I would try to create a 'passive index' for your ideas. How much time will they take to get off the ground, how much to run monthly, what is the product life cycle (if you can work that out!). From when I started there are a HUGE number of resources to help you also. Feel free to ask for help or advice, for what it's worth!
EDIT: I actually met my SourceGuardian partner once in Prague for 2 days. Forgot that when I wrote the above!
