What causes indecisiveness?

That is why it is GOLD to meditate.
In the silence true creative ideas and clear thinking can flow through when the mind chatter is still.
Then, walk, walking clears the mind, for clear thinking.

The meaning you place on you and your actions.
Do you place meaning allot on you and the people you know? in place of just to be with it all as it is or is not?

Yes, we need to lay down a path to follow.
The true is in each moment on the path. You making it mean more, than just changing your mind.
The constant in life is change, else we stay stagnant, stagnant can smell of hanging onto the old and no longer needed.

I always make a list, then the surprise is how it turns out, even better than I would ever have imagined it would, it can take your breath away to be surprised.

Quote for you:
Silent thought, is, after all, the mightiest agent in human affairs.—Channing.

What causes indecisiveness?... Too many choices. Eliminate a few choices and decisions will be easier...
