I need inspiration. How do I get inspired to write songs for my musical?

Well... You can take the inspiration from your own life...

I'm a song writer myself...

If you don't like writing about your own life, try writing about life generally ! What's there to like or hate about it... What does it really mean, try contacting your deep emotions !

Personally, I have a special place where I can think better... Try to find some place calm and relaxing... You wouldn't even have to think, it's like the pen just writes on his own ! Maybe that's your inspiration !

Hope I helped.

You can't make yourself be inspired. Take a pen and notepad everywhere! Write down things that are interesting, fun, lovely, romantic, etc. You'll know exactly when you're inspired to truly write.
