Ecclesiastes 5:2 NAS
Do not be hasty in word or impulsive in thought to bring up a matter in the presence of God. For God is in heaven and you are on the earth ; therefore let your words be few.

Matthew 6:7 NAS
“And when you are praying, do not use meaningless repetition as the Gentiles do, for they suppose that they will be heard for their many words.”

First step to praying well, just say it. Prayer isn’t about length as much as clarity. Some of the best prayers are the simplest prayers.

God,
I love you.
Amen.

Say as much as required. Then stop.

It’s not wrong to pray long, read a Scripture or sing a song,
But when talking to Him who is strong, its ok if your prayer is not long.

The bottom line:
Pray simple.
