I found recently (very recently, to my shame as someone who has been a Christian 15 years), that I can pray so much better outdoors, if I find a quiet area on my own. Thankfully that is pretty easy for me—the local cemetery is always deserted first thing in the morning and last thing at night, and beautiful too.

I think sometimes we take Matthew 6:6 too literally—after all we always read about Jesus going outdoors alone to pray. I personally find it much easier to spend some un-rushed time with God when I leave the house and go for a walk alone.
