Do you have a single idea how BIG is your karma? We're talking about hundreds, thousands, millions of incarnation's actions. Don't expect to collect the fruits of your actual doings in this life.

Research prarabdha karma and sanchita karma. eventually, you will see that accumulating good karma is as troublesome as accumulating the bad ones. Karmas are chains, and good karmas are also chains (and even more dangerous than bad ones).
