I try to choose a place I can be alone without major distractions. This is especially important for me since I have ADD. We have a spare room that works out fine for this purpose.
I also try to choose a time when my wife is resting or doing something else in another part of the house or has gone somewhere.
Try turning off the TV, cell phone, radio, or any other object making distracting noises.
I usually start out by thanking God for His love and for different blessings like life, family, friends, etc, and that I thank Him for His goodness before making my petitions.
It’s also good to just be still and not say anything and just listen for God’s-inspired insights He may give you. The Lord has everything under control, even though it may not seem like it at the time.
I try to have my Bible with me to look up Scripture references that might apply to my current situation.
Note: Even though I’m not Catholic, Catholics speak highly of going to ‘Adoration’. If your local parish has it, I’d highly recommend it.
I went to a local Catholic hospital chapel once while on a visit to see a friend during ‘Adoration’ and it definitely was a quiet time where I felt God’s presence and could focus well spiritually there.
