You need to understand that a skilled professional songwriter can accelerate your success as an already talented musician. These people are writing every single day, so their craft is really sharp, and it's the best songwriters who consistently get on the radio.
I wanted a child, and there was no way I could get pregnant under the stress of 18-hour work days and live TV. When you're somebody who's used to making a decision about what they want to do and getting it and achieving it, when your body fails you, it's a whole other experience.
There's a lot of craft that goes into achieving a hit song - at the beginning of your career, you're usually more inspiration than craft, and you get great when those intersect. A skilled songwriter can get you to that intersection.
