1) I was a hard worker.
2) I was driven – I wanted it badly.
3) I was teachable and willing to learn.
Notice he did NOT say that I wrote hit songs, that my songs were better than the ones on the radio, that I was the best writer he had ever heard, etc. None of those things were true. Still, he predicted success for me based on those 3 factors. If they have those qualities, almost anybody can learn how to write a hit if they put in enough time. Will it happen quickly? Not likely. It took me almost 6 years to get a hit. So, instead of playing me, or anyone else one of your songs and asking if you have what it takes, do a little self-inventory. Ask yourself:
1) How hard and how long am I willing to work at this?
2) How bad do I want it?
3) Am I honestly willing to learn, or do I think I have it all figured out?
The answers to THOSE questions are better gauges of your chances of success in songwriting or in anything you try. Work your tail off, want it with everything you’ve got and soak up every chance to learn. If you do all that, you’ve got this.
