Intentional Words

Is there a way to learn how to pause and think before you speak?

I find I pretty much say whatever is on my mind and I would like to be more intentional with my words.

How could I fit this in the model?

C Speaking words
T ?
F intentional
A pause and think before I respond
R thinking before I speak and saying what I intentionally want too

Iā€™d love some ideas for thoughts that can assist someone in feeling intentional.

One that I have from a meditation is (I move forward calmly and with purpose)

Thank you!!
