If you want to succeed in the music business, dreaming isn't enough. You're going to need a plan. First, you'll need to look honestly at where you are today and where you want to go. You'll need to figure out what resources you have, what resources you'll need to get you where you want to go, and how you're going to acquire those resources. You'll likely need help getting where you want to go. So identifying who can help you and how you can connect with those folks is a crucial part of that plan. As part of that plan, you'll need to make an honest assessment of your talent and skills.
If you want to compete and succeed at the highest levels of the music business, you will absolutely, positively need the talent and skills to do that. You'll need to compare yourself to the artists and professionals at the top of the industry, because that's who you will be competing against. If you don't have the skills and talent today, you'll need to develop those skills and be mindful that the process could take years. If you want to succeed in the music business, you'll need to be lucky for sure, but you'll also need the talent, skills, and an awareness of where you are and where you want to go in a plan to get there.
