Abu Sa`eed al-Khudri said, that the Messenger of Allah (peace be upon him) said:
The Messenger of Allah (Sall’Allahu alayhi wa salam) said (narrated by Jabir bin `Abdullah):“Moses (Alayhi salam) said: O Lord! Teach me something that I can remember You with and I can supplicate You with. Allah said: “Say ‘La ilaha ill Allah’, O Musa.” He (Musa) said: All of your servants say this. He (Allah) said: “If the seven Heavens and those who dwell in them other than Me and the seven Earths are put into one pan (of the scale) and ‘La ilaha ill Allah’ is put into the other; ‘La ilaha ill Allah’ would be heavier.” [Ibn Hibbaan and Haakim]
This is going to max you out at 30-35 minutes of prayer at one time. If you feel like you can do more than that, go for it. If you’re a beginner when it comes to non-liturgical prayer, though, this might be a good way to get started. Whether you’re interested in this approach or not, do spend some time praying about how you’re going to try to grow closer to the Lord this Advent. But don’t stress about it –it’s supposed to be a time of preparation and peace, not frantic anxiety, despite what the mall might do to you this time of year. You might consider starting to read the Bible through in a year using this schedule . Or read Caryll Houselander’s The Reed of God . Just be sure you do something more than bake and shop to prepare for Christmas this year. The Christ Child is coming, after all. Offer him your heart.
