You get all of your neuroses worked out on stage. I haven't actually played very many nice characters, certainly not on stage. It's not a quality that attracts me.
As time went on, I did campaign to lighten the character a little bit, to introduce some romance into the episodes, outside activities, horse riding and fencing and mountaineering.
Roddenberry had created quite a complex and at times mysterious character. Guarded, cautious, careful in showing his feelings in expressing his ideas about many things - I found that very interesting.
