It depends on your age now. If you are 26 1/2 it is going to be hard to be financially independent in 6 months —- Depending on where you expect to live. It would take from US $200,000 (India) to US$20 Million (Monaco) to be financially independent. Financially independent is usually defined as having sufficient income and resources to live comfortably without working at a job.
If you have from 5 to 10 years to make it, any cash you have now to start with is far less important than your skills & motivation. How to do it?
Either get a mentor/role model to help you, or failing that, read “how to” books by people who have actually achieved financially independence. I’d recommend Think Like A Tycoon, but not purely inspirational stuff like Rich Dad Poor Dad. Hope this helps.
