It made me

"Having enough practice and knowledge to be able to capture what's inside me"
How I did it: It took learning and practicing guitar and bass for a year and a half before I reached the point where I could instinctively hit the notes that are in my head, before the germs of the song disappeared. I've also expanded my musical boundaries in that time, listening to more new bands than I have in my life.

Lessons & tips: practice. then work instinctively.
Resources: i found new friends, who encouraged me. I was lucky enough to have a really experienced musical friend invite me to start a musical project playing bass with him, before I'd even picked a bass up.
