Choose the right thing to do, and in that lies success. In that lies immediate success. Immediate success implies that you have been successful right in the moment of the choice itself; you don’t have to wait for the outcome. In fact, if you have to wait for the outcome to determine whether you have been successful or not, then you are already unsuccessful.
Make the right decision. Fight the right battle. Now it doesn’t matter whether you win or not because you are already victorious. Victory lies in choosing the right road to walk.
