Yes, it is common. It usually is used relating to a person needing TIME to do something. Example: “It may take me a bit, but I’ll get the job done” = “I will need some time in order to complete the job, but I will get the job done.” In your sentence, the “bit” refers not to a bit of time, but to a bit of persuasion: “It may take me a bit [it may require some more persuasion] to convince me . . .”

Hey Hazem, how have you been, my friend? In the context concerned, the idiom ''a bit'' means the same as ''a brief amount of time'' / ''a moment'' / '' a short period of time''. So, by saying ''It may take me a bit to be convinced that they don’t want my advice'', you are quite implying that it may take you some time or even a short period of time until you are convinced that they don't want your advice. Below you shall find some other useful examples for a better understanding: E.g.: ''I should be over in five minutes, so I'll see you in a bit!'' E.g.: ''Please, just wait a bit, will you?'' E.g.: ''I can't quite remember the last time she was silent for a bit.'' E.g.: ''It will probably take her a bit to accept the truth.'' Hope that helps!

It is pretty common, and it means "I may need more time." 'A bit' stands for 'a bit of time', and 'take' here means 'use up' or 'need' (it takes time away from you, so you need it). It is used the most when talking about the amount of time you need to either do something or understand something. Example: - It will take me a bit to get ready for the party. - It took me a bit to understand what the teacher said.

The phrase 'a bit' means 'an amount'. In this context it refers to either time or work. So it can either be: It may take me a bit (of time) to be convinced that they don’t want my advice. or It may take me a bit (of work/persuasion) to be convinced that they don’t want my advice.
