It may be difficult to immediately understand how to put Krishna into the center of one's life, but the real science is to just simply change everything that one is doing and instead of doing it for oneself, to do it for Krishna. This does not necessarily mean that renunciation means to give up one's duty or occupation, however; real renunciation is to do it for Krishna. That is the perfection of renunciation.
