Hey Man I have the power ... I hold the power. The power of one!
No-one to please, no-one to answer to, no- one seeking control, no-one to object when I choose boiled eggs or cereal for dinner, when I decide to pull the doona over my head or when I choose to create with gorgeous fabric or write reams till the wee small hours. No-one haggling over how, when, where or why, no-one asking "What's for dinner Darl" or wanting to share the remote or the soap!
No-one wanting favours, my body, my money or my time! I'm in charge.
You can do it too ... if you're feeling powerless, hang in there, realise you have the power to change what's going on. Any power struggle always put's the ball in your court, you can change what hurts, what you object to, what makes you mad, or worse still drives you insane.
Take charge, don't accept bad behaviour, become powerful ... it's all up to you, you're the most important person you know!
