More points to inspire your conversation with God:

• You say that you don't know how to pray? Put yourself in the presence of God, and once you have said, 'Lord, I don't know how to pray!' rest assured that you have begun to do so.  THE WAY, no. 90
• To recollect oneself in prayer, in meditation, is so easy! Jesus doesn’t make us wait. He doesn’t leave us in the waiting-room. It is he who does the waiting. You only have to say “Lord, I want to pray, I want to talk to you!” and you are at once in God’s presence, talking to him. And as if this were not enough, he doesn’t begrudge you his time. He leaves it up to you, just as you please. And not just for ten minutes or a quarter of an hour, but for hours and hours! For the whole day! And he is who he is: the Almighty, the Most Wise.  THE FORGE, no. 539
• You write: 'To pray is to talk with God. But about what?' About what? About Him, about yourself: joys, sorrows, successes and failures, noble ambitions, daily worries, weaknesses! And acts of thanksgiving and petitions: and Love and reparation. In a word: to get to know him and to get to know yourself: 'to get acquainted!'  THE WAY, no. 91
• I have distinguished as it were four stages in our effort to identify ourselves with Christ: seeking him, finding him, getting to know him, loving him. It may seem clear to you that you are only at the first stage. Seek him then, hungrily; seek him within yourselves with all your strength. If you act with determination, I am ready to guarantee that you have already found him, and have begun to get to know him and to love him, and to hold your conversation in heaven.  FRIENDS OF GOD, no. 300
• Remember that prayer does not consist in making pretty speeches, or high-sounding or consoling phrases. Prayer, at times, will be a glance at a picture of Our Lord or of his Mother; sometimes a petition, expressed in words; or offering good works, and the fruits of faithfulness… We have to be like a guard on sentry duty at the gate of God Our Lord: that’s what prayer is. Or like a small dog that lies down at its master’s feet. —Do not mind telling him: Lord, here I am, like a faithful dog; or better still like a little donkey, which will not kick the one who loves him. THE FORGE, no. 73
