I've been working with a number of clients who are all opportunistic. I like to consider myself as opportunistic as anybody, and I've learned that if you're not careful, that trait will kill your business.
Here's my tip - stop doing something. Pick something that you think is important and make the decision that you are not going to do it. Take that time (and, more importantly, energy) and apply it to something else you are already doing (don't add a new thing). I promise you'll see better results faster.
If you feel like it, share what you are going to stop doing in the comments section.
