Perhaps you can return to those questions again later in the day. If you would like to devote more time to prayer and reflection during Advent, consider the following format. It presumes about 15-30 minutes a day. Adapt it to best fit your needs. Not everyone prays at the same time.
Prayer can happen early in the morning, late at night, or at many other conducive times.
The key is to make a commitment to keeping whatever time you choose. After a couple of days, if you find that the time you have picked isn't working, re-negotiate a new time with yourself. Create a Space Pray anywhere you like. Find a place that is conducive for you. You may like to go to a chapel or to St. John's.
