Yay! I think I made a mistake

All the pros talk about learning from your mistakes. It always bothered me that I don't think I learn from my mistakes.
I'm excited today because I think I found a mistake and I think I learnt something from it. I decided to go with the approach of waiting for 400/500 clicks on campaign to asess it's profitability. I put up two campaigns so far. One of them has 120 keywords. Since April 8 I got 150 clicks on this campaign with a CTR of 2.5%. It's just taking forever to reach that 400 clicks goal.
So I think when I start a campaign I need to set myself a goal for a minimum amount of keywords. That amount should be significant - Say 500-1000. I'll have to look into this.
A way to do that is to follow Amit's advice to start with breadth keyword research.
I'm getting the impressions so I need to improve CTR:
- By making sure I'm higher than the 8th position
- Perhaps Improving ad copy and the like (not sure about this one yet)

These steps should probably help me reach that 400 clicks goal much sooner.

Good luck
