How can I make 6lakh/year.

If I can earn 6lakh/year I am in self sustainable mode and I can continue practice until I am done.

How can I make 6lakh/year and move in a positive direction. You best bet is to do freelance work as a full stack software engineer. This way you are growing yourself and you can make enough money.

The second option seems to be training. I can engage with mountblue, or I can also engage with synechron. If you work 2-3 months fulltime, You can take training classes. You can build small service or product. It is also possible to engage fulltime after practicing for an year.

It can also be possible to work fulltime for 3months and earn maybe 10lakh and then go off for next one year.

Ideally I should be very good in full stack programming and then I can work on a platform like toptal. Do some project and then continue your practice. this way you can keep upgrading yourself and you can continue practicing.
