i am 74 years old now, and feel i have some interesting stories to tell school days, 10 years in RAF, my various business after the RAF, and my hobbies such as Lawn Bowls achievements Masonic interests also, my Father had 24 years in the RAF, which he did put in print more particulary his experience in the 2nd World War which is quite interesting, I hope you can help me with putting something together mainly for my familiy and friends.
First thing you can try is write down your memories as if you were telling them so you can get a feel for your own style of writing, the other thing that could help if read real-life stories and autobiographies from people you like to see how they have written about their past, last bit of help I can give is read books that are written in first person. Hope this helps.
Another little tip; reread what you write, and keep an eye on your grammar, it could be better.
