When you have found something which has the power to help you in gaining a victory over your unconsciousness and inertia, you must, till you reach the final result, exhaust all the effects produced by that word or phrase before you look for others.
It is more important to pursue to its end the practice of the effect produced by an idea that one has met somehow, than to try to accumulate in the head a large number of ideas. Ideas may all be very useful in their own time, if they are allowed in at the opportune moment, particularly if you carry to the extreme limit the result of one of those dynamic ideas that capable of making you win an victory. That is to say, one should have for one's chief, if not only aim the practice of what one knows rather than the accumulation in oneself of a knowledge which remains purely theoretical.
So one could sum up: put into practice integrally what you know, only then can you usefully increase your theoretical knowledge.
