Because the pronoun one has gone out of fashion or is considered higher diction than some writers wish to use in their writing, many students are unsure of how to use the pronoun one correctly or what, in today's gender inclusive thinking, the correct possessive form is.  The correct possessive form is one's, which can become awkward sounding if one is using it frequently.  As is often the case with pronoun usage, a complete recasting of the sentence may be necessary to make the usage sound more natural. Also, as you practice using one in your writing, it will become more natural sounding.
