Don't be scared to pray out loud with or for others.
For me it was, and still is to an extent, difficult to pray out loud in front of others. I always feel the need to sound "Biblical" when I pray, to use big words, apply powerful pauses...it's just not who I am.
Romans 8:26 reminds us that : "For we do not know what to pray for as we ought, but the Spirit himself intercedes for us with groanings too deep for words."
This is a constantly good reminder for me. I don't need to be poetic with my prayers, the Spirit intercedes for me and God ultimately knows what and who I am praying for. So next time you have the opportunity, don't be afraid to pray out loud with others …the Spirit has you.
