What is my biggest "why" (the deeper purpose or motivation behind my intentions)?

That is the desire to fill my inner lack behind all decisions.
I think that everyone has lack of each differ something. = experiences a different lack in their lives.
So, we feel thirsty from lack, while we aren't satisfied about = with abundant things.
That's why we lay aside lots endures to make more wealthy in our life = of things to become wealthier.
My biggest lack is the stability, which guide = guides me on any occasions = occasion.
I am anxious and uneasy person naturally, and have had some experiences to deal = dealing with the adversity alone.
It makes me to do training = has trained me to be ready for the suffering.
Consequently, I want to be more rich, strong, independent, and objective = richer, stronger, more independent, and more objective for my iron stability.

Thank you for reading!

My desire to fill an inner void drives all my decisions. I believe that everyone experiences a different lack in their lives. We often feel thirsty for something we lack, even when we are surrounded by abundance. This longing leads us to set aside many things in our pursuit of wealth and fulfillment.

For me, my greatest lack is stability, which influences my choices in every situation. I tend to be anxious and uneasy by nature, having faced adversity on my own. This has motivated me to train myself to be prepared for suffering. As a result, I strive to become richer, stronger, more independent, and more focused on achieving my goal of ironclad stability.
