Why do I have that Bible quote from Luke 5:4 ?

After years of recording music, some unfortunate collaborations and hard musician's life I was ready to give up and move on to a "real" job. Then one day I received a newsletter from Derek Prince Ministries with the story how Jesus told the apostles to go catch some fish. They protested , saying we have tried that spot , there is no fish over there. Jesus said: go, because now I'm telling you to go and catch the fish. So they went and returned with full nets.

I felt like I tried and fished (read made music) and never came back with full nets. But then, later He told me "Go again, because now I'm telling you to go".
