Having a bad day? Looking for something to lift your spirits? Try listening to music that you like...or more specifically, listen to songs that you heard a lot during a good time in your life. It can make you feel like you're going into a time machine, like you're going back into a time that was good for you and puts a smile on your face. I find doing this often lifts my spirits, especially if the song is not only from a good time in my life, but is a song I haven't heard in a long time.
