As is known, to avoid excessive use of we is not an easy task, especially if we also wish to avoid the passive voice, but some style guidelines says that not only one should avoid excessive use of we, but also the excessive use of I.
Since I found that wegotism is defined as 'Excessive use of the pronoun we; - called also weism,' I'm wondering whether there is a word meaning 'excessive use of the pronoun I'.
I attempted to find 'iism' without luck.
So, my question is, what do you call the 'excessive use of I' in speech or in writing?
