I second, third or whatever the advice to focus on where you want to go and not on the obstacles you want to avoid.

Years ago there was a hilarious episode of Frasier in which he was trying to learn to ride a bike. Unfortunately, he kept focusing on the obstacles ahead of him (eg, tree, mailbox, etc). And, the eye-mind-body link being what it is, he kept running into the obstacles despite large clear paths around them. Similarly, my nephew was a pole vaulter and was frustrated that he couldn't clear a certain height. I asked him where his eyes were focused and he said "on the pole". I told him to focus a couple feet above the bar. He did and from that point on was able to clear the bar.
