“Not only do I knock ’em out, I pick the round.”

Simplified Meaning:

When someone is bragging about their abilities, this means they are so confident in their skills that they can predict exactly what will happen and when. Imagine a skilled boxer who isn't just saying they will win the match, but they are also telling you they know which round they will win in. They have so much belief in their power and timing that they can foresee the exact moment of their victory. For example, think of a student who always gets top marks in exams. Instead of just saying they will ace the exam, they boldly tell everyone they will score 100% and get their top marks specifically in certain parts of the exam. This shows they trust in their knowledge and preparation so completely that they can predict the exact details of their success. This idea can be used in anyone’s life by not just aiming to achieve goals but by having such strong confidence and mastery over their skills that they can foresee the exact outcomes and timings of their achievements. It’s like planning your path to success and sticking to it with high assurance.
