"One way in which you can get the determination to go out and distribute books is by hearing. There are no obstacles if you have the desire. Although the mind will find excuses—because that is the nature of the mind—we simply have to become stronger and defeat all the excuses that the mind will offer with the strength of purified intelligence. If we have a strong desire to do something which is very pleasing to Guru and Krishna, then Krishna will help us to overcome the obstacles. However, if we try to overcome the obstacles by our own endeavors alone, we will always fail. We cannot be successful in such endeavors. A devotee always has to be dependent upon the mercy of the Lord. That is one of the symptoms of surrender.
