Just start from where you are and build your skills up from there.

Example of Skill-levels:
Level 0 = no skills for generating passive income
Level 1 = your first 1K earned online. Yeah this feeling is awesome!
Level 2 = your first 10K earned online
Level 3 = your first 100K earned online and then keep on growing

What i mean with passive income is that you are able to earning money via an automated system in a different moment in time, without you being physical present. So you are NOT trading money for your personal time in the same period.

This for example could be online via the internet, with for example developing Affiliate (Referral) Marketing Skills, like the big companies do (Amazon, Bol, DropBox etc.)
