Why do you compose?

He guys, I am doing a report on music creation. I thought it would be good to get insight from other composers. My questions are,

1. How do you feel when you create music?
2. how much time do you spend on one piece?
3. why do you create music?

I would really appreciate honest sincere feed back. any advice for writing this essay would be much appreciated. Thanks

Every question can have too many answers for me, so I make the questions more specific to me:

1. This question is for me like ,,how do you feel in life?'' My emotions when makeing music depend on how my day is. Maybe you mean: ,,What feelings does composing muisc give you?'' Then my answer is that I can relieve my emotions through music. I also like to write about my feelings so that I can understand them more easily.
2. That depends on how long a piece will be and for how many instruments you need to write for. An overture with a duration of circa 7 min for 13 musicians took me more than 180 hours.
3. I feel that I need to write muisc down. Otherwise, it ruins my mood and I become sick. Music is my greatest love in life.
