stuck in a loop… purpose for wanting

Hello, I’m new to SCS and am getting stuck with the idea of wanting something or setting goals. I understand that the only reason we ever want something is because of the way we think it is going to make us feel. We can also create those feelings with our thoughts now without pursuing or achieving the goal. Holding these truths, how and why do we chose to go after something? What is the motivation/point if we can create the end goal with our thoughts?
If this is unclear, I’d be happy to explain more through a coaching call or tutor. Thank you!
