"私は成功したいという渇望と願望を持っていて、それを邪魔するものは何も許さないつもりでした"

Simplified Meaning:

Someone wanted to achieve something very important to them, and they felt a strong urge to succeed no matter what. They were determined and didn't let any obstacles or difficulties stop them from reaching their goal. Imagine a student who dreams of becoming a doctor. This student studies hard every day, even when they are tired or their friends are out having fun. They might face many challenges, like failing a test or struggling with a tough subject, but they keep going because they really want to be a doctor. The student’s drive and determination help them overcome every problem until they eventually achieve their dream. This kind of mindset shows that if you want something badly enough and are willing to work hard and not give up, you can achieve great things. People can use this attitude in their own lives by staying focused on their goals and pushing through any challenges along the way.
