The point is, the Indian system is tough because of competition and when you get early success then you have to perform consistently for the next 10-15 tests as well otherwise someone else will replace you.
This is one of the reasons why more and more cricketers are shifting their time and resources to the T20 format since they stand to earn more money and popularity in a way shorter period without worrying too much about other factors.
Honestly, I would do the same because time is money. Test cricket is great for several reasons, but it requires a huge time+effort investment.
