Savor your experiences with friends, but also 'mix-up' the time you are home alone. Take notice of your alone time and appreciate the ability to do the things you have wanted to do. Try something new or add something different [burn incense, write, play music, DANCE (even if alone)]. Don't make it all about your 'to-do' list.
The important thing is: don't get in a rut. Appreciate what you have, and think about how to enhance it. Make the most of all of your experiences.
