Have good intentions in all you do ; Perform acts with sincerity ; Understand how your intention affects your reward from Allah SWT .

This hadith explains that our actions are determined by our intentions. Our intentions determine the reward we will receive for our actions. For example, if someone emigrates to a new country for the sake of Allah and His Messenger, then their emigration is considered an act of worship and they will be rewarded accordingly. However, if someone emigrates to a new country for worldly gain or to marry someone, then their intention was not pure and so they will not receive as much reward as those who had good intentions when performing the same action. This teaches us that it is important to have good intentions in all that we do in order to reap its rewards in this life and the hereafter. It also reminds us that even small acts can have great rewards if done with sincerity and purity of heart.
