I was much more interested in the orchestra than the piano, but I did become fairly proficient as a pianist and my teachers felt I had talent and wanted me to become a good concert pianist and earn my living that way. ↗
In symphonic music, when you are conducting, you do the same thing. You are feeling the whole orchestra, thinking ahead so you can prepare for a change. ↗
A conductor can do wild things which can feel forced, but if you're directing from within the orchestra, you can't do that, things have to feel natural. ↗
And, all these things need to be coordinated; so we all need to work together, have timers going and everything so we're all coordinated and get this piece of orchestration done. ↗
I used to play works in progress to people, but now I wait 'til it's finished, because you make excuses all the time: 'Well, there's gonna be an orchestra on it.' Rather than make excuses, wait 'til it's finished, and then they can say they don't like it. ↗
