Bullshit. I find travel very stressful, and none of it is due to fear of change and different experiences. It comes from living out of a suitcase, having to re-buy all the toiletries and crap I have at home but forgot to bring, and being away from my wife and dogs who I enjoy spending time with.
Just remember: don't like != am afraid of I don't like buttermilk biscuits. That doesn't mean I wake up sweating in the night screaming that they're coming to get me.
