I'm no stranger to change, and as much as it makes me uncomfortable when a new experience comes along, I've come to accept that change is a natural part of life.
This did not come easily to me when I was younger, and any sort of change was met with much resistance and much kicking and screaming into a future that was going to happen without my complete control.
One of my biggest learnings is that we use as much energy resisting change as we do being unhappy with the things we don't like or want, so logically it makes sense to channel our energy into something new and creative, wouldn't you think?
If you've made a New Year's resolution then you too have put your hand up for something to change. However, if at the first sign of discomfort you've scuttled back to the familiar then you may miss the opportunity.
You won't know until you try it. A good question to always ask yourself is "what's the worst thing that can happen?" and if it's worse than what you are already experiencing then perhaps consider taking a smaller step.
