What should someone who has become bored and despondent with obedience after committing to it do?

You must thank Allah for the blessing of commitment to maintaining what pleases Him in word, deed, and belief, while being wary of the whispers of Satan, the weakness of the self, and laziness. It is advised to seek Allah's help with sincerity and devotion so that He may aid you in remembering Him, thanking Him, and worshipping Him well. With patience, hardship will vanish, and worship will become a source of comfort, happiness, and tranquility.
