Do not beat yourself up for days you miss. Just wake up 15 minutes earlier than you would and take this time all by yourself. Pray for the grace to fulfill the goals of your meditation practice. As a beginner, if you find meditation difficult using one of the focus techniques described above, you may use music as your focus. Play the music.
Some techniques use soft music.
Others use loud music because it vibrates within the body and helps to overwhelm ordinary thinking processes. Keep returning your mind to each note of the music. Do not listen to the melody or structure of the music. Then, just as with any focus technique, you may notice thoughts, feelings, body sensations, sights, etc. Just let those things be and keep returning your mind to the music.
