Remember, your success depends on the inward state of your mind. Your mind will create hindrance in your work if it is not in communion with God because He alone is the permanent abode of peace. Yes, I agree that most of us want to have riches, healthy lives, nice children and prosperous future. But if we always approached God with a begging attitude then we are treating Him as our bearer to supply the things required by us at once. This is no devotion to God but devotion to our own selfish desires.
