What if I had made a different pivotal decision in my past? Which decision would have changed the course of my life?

I think I have no pivotal decision in my past, because = past because I am young untill = enough to make any crucial decision changing = that changes my life.
But I am regrettable about my past decisions and want to change something.
My personality is skittish and oriented stability, so I take a passive choice of many courses.
That's why I have less experiences = experience compared with extrover = to my extroverted friends.
It follow me = follows my narrow view of life, so I think I couldn't grow up to be a mature woman, although I can.
If possible, I would change my determining way to pursue new and challenging opportunities.
Then I can experience a new world, including both joy and sorrow.
I tend to think I must enjoy my life because I can live just once, when = as I am getting order.
I try to be a woman of ripe experience.

Thank you for reading. See you soon!

I believe I haven’t made any pivotal decisions in my past, as I am still young enough to make significant choices that could change my life. However, I do have some regrets about my past decisions and wish I could change a few things. My personality tends to be skittish and oriented toward stability, which leads me to make passive choices among various options. As a result, I have less experience compared to my more extroverted friends. This narrow view of life makes me feel as though I haven’t matured as much as I could have. If possible, I would like to change my approach and actively pursue new and challenging opportunities. I want to explore a broader world that includes both joy and sorrow. I often remind myself that I need to enjoy life because I only live once, especially as I grow older. I strive to become a woman with rich experiences.
