Thoughts may be free, but it doesn't mean they don't have a cost.
Sometime I just sit and think. Yes, its true. Sometimes I just let the thoughts run through my head as if they knew where they were headed. They dance through my mind while I just sit quietly, watching them follow each other, one after the other.
Thoughts are things. Think about it. They can come in the form of contemplation, consideration, musing, reflection, deliberation and more. They inspire actions and inaction. Just think how different things might be if people just took a moment to think before they spoke! Some people are thinking the darnedest things. It doesn't mean you have to give voice to them.
So I think that it is wise to let the thoughts continue to do their thing. We are always thinking. Always. No matter what we are doing. We are thinking while we are doing it. Of course, it doesn't mean we are thinking about what we are doing. And that could be part of the problem. Think about what you are doing while you are doing it and you might just think twice. So many people these days don't seem to see the disconnect between their thoughts and their actions.
So think about it, please. I think if you do think long enough, you will agree. It's all in what you think about it. And that's a thought worth thinking about.
