Making good deeds a habit

Imam Sadiq (as) is quoted to have said:
“I like to continue good actions so that I become habitual in them. If I could not perform a particular deed in the day I make up for it during the night and if I do not perform an action during the night I make up the following day. Certainly the best of the deeds near Allah are those which one continues. Hence all the deeds of the week are presented to Imam (a.s.) every Thursday and the deeds of the month at the end of the month and all the deeds of the year at the middle of Shabān. So if you begin a good ritual, keep at it for the whole year.” (i.e. continue it for at least a year).
