Since the age of 14 I played just for fun guitar, base guitar (in a band, because I was so bad at the guitar, that they let rather the base player play guitar and thought I do less damage to the music at the base), various percussion instruments and the piano and used to sing my own songs. And I was bad at each musical discipline. Kind of a musical duck. Like they can fly and swimm and walk, but none of it really well.
But I believe, I am not bad at song writing.
But if I had a free wish for being good as a musician, I wish I were a good singer.
