In my opinion it does work. You just need to be open to multiple ideas and only choose the best ones.

For example I went to Thailand and saw the popularity of rolled ice-cream.

In my country that doesn’t exist at all. Rolled ice cream uses the same phycology as subway meaning there’s a huge opportunity in my home country to capitalise on it.

You just need to look harder and be open to things that may seem unconventional

Depending on your job you have a few options. Personally I reckon finding a income stream where you only have to manage is the best.

For example if you manage rental properties for landlords you only need to spend 4-5hrs a week and you’ll get a steady income stream.

Only downside is you need to find people willing to hire you based on no experience

The best way to find the best ideas is to travel.

Go to other countries, see what’s popular there and if it’s already in your home country.

9/10 it’s not and is a huge opportunity for a market

You could start offering personalised self development programs. They’re easy enough to make and your pretty much copying and pasting for multiple people
