Life is not a constant thing. Change is actually the normal, inevitable and unavoidable nature of the universe. Stability and predictability, while nice to have, are illusions easily shattered when life intrudes. You can fill in your own examples to illustrate my point [birth, death, illness, accident, new iPhone].
One aspect of living in a changing universe that I have been thinking about recently is on which side of the training/learning coin do I sit. Do I look at every new thing as something to be learned or do I expect life to come with a manual and a trainer?
My own view is that I prefer to look at every new thing as something to be learned, something to pull apart, press all the buttons - a new toy to occupy my mind. Not just because I don't want to read the manual but because I learn more that way and it is more fun - though sometimes I read the manual as well! In fact reading the manual or asking someone for help is just another way of learning - it just depends on how you look at it.
I'd encourage you to consider your perspective on new things. Do you learn or want to be trained?
