being Howard Roark

well i started reading Fountain Head novel by Ayn Rand.I hav been longing to read this book for quite a time now.
so the hero of the book is Howard Roark.Well he is quite a weirdo but an accomplisher.What's wrong with him is he never change for some one(well some may say thats the plus point).i hav the same doubt??
How gud is to be arrogant to the clients who come upto u seeking your valuable ideas and inturn when u r gettin paid for that...?
He is an architect and if i remember correctly,these r his words:' i design buildings for clients to accept them but not approach clients to design buildings'.well in the end what helped him is just his talent i wud say.
But what if one posesses equally gud talent and holds a convival relation with his clients??i wud say he will bethe best...
