By learning every single noun and what gender it is. "Мой" is a male pronoun which is used with male nouns. Same goes for "моя" (female) and "моё" (neutral). Most female nouns in Russian end with the letters -а/-я (весна, душа, пустыня) or the letter -ь which makes the previous letter soft but is not pronounced (мысль, ночь). Thus, it'd be "моя весна, моя душа, моя мысль, моя ночь" etc. Most neutral nouns end with the letters -о/-e (окно, пианино, пальто, ведро, болото, золото, солнце, озеро, варенье), means "моё окно, моё солнце" etc. But beware that the male nouns can be also made the very same way as the female ones, they can have the same ending vowels (дядя, папа), or the other way: not having vowel letter at the end which also means that it's a male (сон, нож, муж). Unless you were born here, you should learn every word to make sure it's the right gender. And the gender of a noun can change depending on the context. For example, we can say "плакса" speaking of a boy, though originally it's a female noun meaning a person who cries a lot. I am really sorry for those who want to learn Russian. It's a challenge I wouldn't except if I were not born here. I hope I helped at least a little (though it seems like I made things only more complicated). Anyway, good luck!
