For me, one refreshing way to end a full and busy day is to listen to music.
Doing this makes me relax as well as reflect a bit on what has happened during the day. I try take note of the any “lesson” of the day as well as what would be the things that would need my attention and focus for the next one. This is when I also take the time to thank the Lord for the day and to ask His guidance for the next day.
The usual music I would listen to would be instrumental music — specifically Christian soaking music. Check out this one playlist that I have recently been using, perhaps this will also be refreshing for you too 🙂
