Let's say you have expressed your concern to your boss as a call center agent, regarding holding back (you are a non-native English speaker). You say:
I've got no plans of holding back when expressing myself in English. I want to use English to converse with my co-workers. I don't like holding myself back speaking in English just for the sake of saying to them that I know how to blend in.
For clarity: "holding back" as a non-native English speaker who work as a call center agent means every time a problem occurs at work, you verbal it out in English instead of using your 1st language. Your co-workers might see this behaviour as bragging because you express your concerns in English.
Some say that the bold letters are phrased unusually. I think there is a fixed phrase to express this idea, but I can't get the phrase out in English.
