Do you have trouble focussing on other things? Prayer is just talking to God. Use the Lord's prayer as a pattern - praising Him, and telling Him how much He means to you and thanking Him for the good things you have in life. Start counting off your blessings and then saying thanks alot. Then pray for whatever it is you think might be His will for your life and ask Him what gift you have to use in the Church. If you don't know what the gifts are, there is a list in Romans 12 and 1 Corinthians 12. Pray for your parents, family, and friends - government, freedom, Israel, the world, against war, for the poor and needy....??...then swing it back around again and just lift your hands up to God and adore and praise Him with your love again.....
This may not be your way, and there a many ways to pray as there are people, but you will develop a way as you pray more. We can carry on a silent prayer with God throughout the day, practising His presence because He never leaves us, and I think this is what the Bible means with "pray without ceasing".
You can also recite His promises back to Him and claim them for your life, saying that you want them. Get your Bible out and talk to Him about it as you read. There are lots of ways.......I hope this helps you out some.
God bless
