There is a slight difference between

To think to oneself:

To have an inner monologue; to make a statement to oneself in one's mind, without saying it out loud

and "to tell to yourself":

to make yourself consider something in order to understand it correctly or to persuade yourself that it is true

The Persian idiom here means the former not the latter.
