Being is a steady state. I am what I am and I’m ok with it (or not) – get over it.
Becoming is more action oriented than being. It implies progress. Change.
There’s nothing wrong with a steady state, but in a world of change, shouldn’t you be prepared to modify your point of view?
Aren’t there new ideas and viewpoints that might help you improve your current situation/mindset?
Becoming gives you space to be more than you currently are – and, unless you’re perfect (and who is) shouldn’t we try all try to be more?
What are you becoming?
