I just stop looking at bitcoin price. It hurts me actually, that's why I took this decision. I am holding few of BTC and I will not look at my wallets too for 2 months. I hope after 2 months when I will go to see bitcoin price, maybe I will scream happily. What about you guys? 
As a holder, I think I also have the same problem of not being able to do without keeping tabs on the price of bitcoin.
However, I believe your decision is a very good one as it will eliminate the pain and disappointment one gets every time one checks the price of bitcoin and see and it is still below expectation.
I think I'll have to make use of your method in order to save myself from this everyday disappointment.
