I really hate PPC.

As far as I know it, it seems to me that PPC is probably the most difficult marketing exercise on the net.
Why is it so difficult to convert more clicks into sales when the CTR is so high?(a whopping 9.87%,90 clicks 1 sale)
The keywords i have been targeting is always the brand name.
Anyone has any insights and suggestions?
Thanks.
