Wrong time to bluff?

[mjohnson406]

After this hand, the villian starts harassing me, saying this was a horrible move. I told him I just wanted the pot and I was continuing my pre flop aggressiveness. Now if I had missed my 7-outer, he would be happy as hell with my bluff. Was the move wrong and next time I make a play at a pot, should I over bet his stack or bet maybe 2/3rds of it?
