Stand firm, and   -- (PP3) The Greek words meaning "in that patience of yours" here are not translated but instead their assumed meaning is paraphrased into different words. The word translated as "in" also means "within", "with" or "among". The word translated as "your" is plural addressing a group of Jesus's listeners. The Greek definite article, "the", usually precedes a noun or changes the word it precedes (adjective, infinitive, participle, etc.) to act like a noun. The Greek article is much closer to our demonstrative pronouns ("this", "that", "these" and "those"). See this article for more.  "Patience" is an  uncommon word, a noun meaning, "remaining beautiful", "endurance",  in bad sense, "obstinacy", of plants, "power to endure" and "enduring to do". "Endurance" is a better translation than "patience". This word is used to describe the ability of plants to endure, which we would call "hardiness". It follows the noun, which is optional and so intentional,  so "of yours" is more correct.

you -- This is from the second-person, plural form of the verb.

will -- This helping verb "will" indicates the verb is in the future tense. Helping or auxiliary verbs are needed to translate the Greek verb forms into English. However, the verb could also be in the form of possibility, "might".

win -- The term translated as "win" means "to acquire," but specifically for yourself. It also means "to possess" in the sense of having something stored in opposition to the common Greek word that means "possess" in the sense of having it in hand. This is in the future tense.

missing "yourselves"-- (WV) A phrase is necessary because the form of the previous verb is a middle voice, which means that the subject is to  act on "yourselves", "for yourselves" or "by yourselves".

your -- The word translated as "your" is a plural addressing a group of Jesus's listeners. It follows the noun, which is optional and so intentional, so "of yours" is more correct. 

missing "the/these"  -- (MW) The untranslated word is the Greek definite article, "the", which usually precedes a noun or changes the word it precedes (adjective, infinitive, participle, etc.) to act like a noun. The Greek article is much closer to our demonstrative pronouns ("this", "that", "these" and "those"). See this article for more.

life -- (CW) The word translated here as "life" is psyche, a common word in Greek, familiar in English, translated commonly as "life", "soul", "consciousness" and "a sense of self". It is used for different aspects of "self", the emotional self, the conscious self, the intellectual self. Jesus uses it to mean our identity in our worldly life specifically, the role we play on earth, what we might call the "self", "ego" or our "the person we are". The problem with translating it as "life" is that another common Greek word means "life." The problem with "soul" is that it doesn't work for many verses because the "soul" is separate from the body. Though the word can mean a departed spirit, most of the word's meanings revolve around "self". "Soul" can also be confused with the concept of "spirit" which is another Greek word. When "self" doesn't work, "person" offers the least confusion. See this article for detail about this word.
