You said a very very important thing...
That is "a income should come whether i work or not"
Hence a Passive cashflow (not Active like a job as a employee or as a Self-employed doing a small business)
Small Business = If owner doesn't work for a month the business fails.
Big Business = Owner doesn't have to work.
So a Big business differs from a small Business not from the amount of income but from owner's time coz its measured in Potential.
a Doctor having a dispensary is a small business. His income is limited to him working 24 hours.
But "iCOM" is a Big business as you are not working the potential of this is unlimited! You can open 5 more shops in your district, 50 more in SL, 500 more in India and so on...If your SYSTEM is strong and you are willing to THINK BIG!
All the Best Machan!
