Krishna consciousness is like running a marathon race. It is a long race so you have to pace yourself. In a marathon the runner does not sprint at the start or middle but rather the sprint occurs towards the finish of the race. Similarly in Krishna consciousness we have to start and gradually progress one step at a time. It might be slow but surely has to be steady. One thing is for sure if you want to finish the race successfully there is no question of stepping backwards. It is better to practice Krishna consciousness gradually and progress in one direction than going back and forth. We have to determine our mind that Krishna Consciousness is a one way street to Goloka. Once you are on it - no returning back. This should be our conviction.
