We are commanded to pray:

And he spoke a parable unto them to this end, that men ought always to pray, and not to faint; Luk 18:1 Praying in the Spirit.

Pray without ceasing. 1Th 5:17 We ought to walk in awareness of the Holy Spirit in us such that all our thoughts are shared with Him and processed in accordance with His Word.      In so doing, we pray without ceasing.      Prayer is communication with the Holy Spirit.     Since we are in partnership with the Holy Spirit keeping the lines of communication open is critical for the successful operation of the partnership.      Think of how a singing duet must be aware of what each other is doing in order for them to hit the right note and the right syllable at the same time to produce harmony.      Praying is harmonizing with the Holy Spirit.

But prayer should not be forced and it should not be uncomfortable or insincere.   

Therefore obeying the command to pray requires that we become oriented toward prayer so that it is natural and flows from a desire to pray and recognition of the fellowship it represents.   

I see believers all the time that are reluctant to pray in public.   I have no idea about their private prayer life but that reluctance is indicative of a problem.   
   ➛ thanksgiving should be part of our consciousness
   ➛ praise should always be on our lips
   ➛ when we pray we develop patterns which should be readily available

The opportunity to pray should be seen as an opportunity to testify of the Lord Jesus Christ and His blessings upon you.   

When you are done saying something specific, say Amen.   
Otherwise, you fall into the pharisee's style of praying which is religious and not relational.   

Flowing In Prayer is a result of
   ➛ thankfulness
   ➛ praisefulness
   ➛ faithfulness

So, if you are not Flowing In Prayer you need to spend time
   ➛ thinking about all your blessings,
   ➛ thinking about how great, good and loving God is,
   ➛ reading His Word to build up your faith and
   ➛ praying in the Spirit to build up your most holy faith.   

By practicing these you will build up a repertoire of things to mention in prayer so that you have to choose how much you share in any prayer you pray.
