Personal essays come in all kinds. Some are forms of reportage, such as those by John McPhee or Tracy Kidder, telling the truths about people they've interviewed yet injecting the honesty of the reporter's perception rather than trying to pretend a writer has no slant that skews a story. Other essays deal with decisions made, such as when you finally decide to make a baby and Cheryl leaves her diaphragm out for the first time in 14 years and you laugh as you remember getting sick of her mom asking about grandkids and telling her you both wanted to get really good at sex before doing it for real and now here you are for real and scared if you'll be good enough, and you're not talking just about sex now. Essays can also be speculative: questions about found objects, thoughts about missed opportunities and things that never were, or memories that haunt you such as Lindsey in Washington, ., who lived in an all-women's house that banned men and made you stand outside in the snow when you came over to get some banjo books abandoned by a former tenant but something happened and Lindsey moved into your room the weekend you hitched down to North Carolina as bodyguard and companion to her friend Rose and stayed when you got back to hump you two or three times a night until you got so raw you could hardly walk and with no talk or even real emotion of love or commitment to prevent you leaving a month later, but now you remember how there also wasn't any talk of contraception because you'd assumed she took care of it since she was so much older, yet now you jerk awake in the middle of the night years later with the stark realization that a lesbian has no need of IUDs or diaphragms or the pill but she does need something to make a baby of her own and maybe there's a little Stan Junior walking around someplace who is 6 years older now than you were then and you wonder if he's as naive as you suddenly discover you were (probably still are) and the only minuscule iota of relief you can find is that at least you'll never have to give him that man-to-man about the birds and bees. By baring your life, using concrete situations and honest thoughts, and following the basic rules of grammar and composition, you too can write a personal essay in 25 sentences.
