This question tests the understanding of the phrase 'deliberately press into ourselves' in the context of habit formation. The correct answer is B, as 'deliberately' implies intentional action is required to form new habits. Option A is incorrect because it suggests accidental formation, which contradicts the idea of deliberate action. Option C is wrong because it implies a lack of awareness, which is not supported by the phrase. Option D is incorrect because it suggests that the process is uncontrollable, which is contrary to the idea of deliberate effort.
