Sometimes we think we're stuck - stuck in a job we no longer enjoy; stuck in an unfulfilling relationship, or whatever the case may be - when in reality, we're afraid of what it would take to change the situation, or afraid of what our life might be like once we did, or perhaps we're simply afraid of regret.
Regardless of the circumstance, fear has a way of keeping us frozen in conditions we no longer wish to be in. But if we can muster up the courage to confront that fear and push beyond it, we'll see it for what it really is.
Just a thought we keep thinking.
Thoughts come, thoughts go. It's only when we hold onto them, turning them into beliefs, that they become stumbling blocks.
