I'm so happy for you Simon, I'll keep all my fingers, my toes and my eyes crossed fro you!!! All though I don't think you need it, you will do great!!! I know you will, you have so much passion and that is a key ingredient for success. Things aren't always going to be good and when the money runs out you will need the passion to survive... and maybe your sister does not have that???
I can understand that you don't want her to sing to... I have a sister and we are very alike, but I hate it when she does the same things as me, even if it's just bying the same pair of shoes...
To me it's like she is trying to take my identity, like she is trying to ruin my uniqueness... I don't know what it is, but I always want to break free of my family and I don't want her to be the same as me because I think I'm also scared that people might think that I'm copying her instead of the other way around....
But good luck, and "may the force be with you"
Love ya
