a fine line

so, where is the line between being conceited and just telling the truth?

i had a kick ass rehearsal today. i was on fire. i was excellent. am i being conceited by saying that?

we (john and i) were talking about the guy who plays my brother in the show and john says i blow him off the stage. i asked him how and he said in articulation, volume, intelligence, stuff like that. (just a side note, i questioned the intelligence comment because i'm not playing an intelligent character, and neither is he, so i'm not sure how that comes across, john says it does and it makes it better, i'm still not entirely clear on that bit.)

anyway, i said i thought in truth i was just generally a better actor than he was. then i felt really conceited for saying that. but i do think that. and fair enough really, i went to school for theatre, he didn't, there is no reason why i shouldn't be better, and i'm not saying he's bad, he's got good stage presence and he's found his character and all that stuff, i'm just a bit more proficient at it is all.

so, here's my question, is it conceited for me to say i think i'm a better actor than him?
