Re-assessing my commitments

A friend of mine made a comment to me yesterday about me needing to take time to reassess my commitments. It struck a deep chord with me.

I realized that I've significantly scaled back my interactions with

friends:
Many of whom I haven't seen in months; some of whom I haven't talked to in years...

family:
I used to call everyone on a weekly basis, and now I send a few email updates a month...

volunteer organizations:
I am taking a hiatus from Search and Rescue Global 1 because I don't feel like I can commit appropriately and I don't want my lack of commitment to affect the safety and professionalism of the other members of the group.
I am thinking about severing my official Big Sister relationship with Little Lisa because she is struggling so much, and I so miss that girl.

(Both of these organizations are amazing organizations - I have been involved with them for 4 and 6 years, respectively. I just don't have the energy or desire to do this right now.)

exercise:
OMG! I can't remember the last time I rode a bike (two years, perhaps?). I run/do the gym maybe once a week at the most. I used feel be so active - working out for at least an hour daily. And I loved the way that I felt. Where is my motivation??? How can it just disappear?

Interesting that my horoscope this week says the following:

ARIES (March 21-April 19): "Any idiot can face a crisis," said Russian writer Anton Chekhov. "It is the day-to-day living that wears you out." Your main assignment in the coming weeks, Aries, will be to use your ingenuity to keep from being burned out by the subtle and minor trials of the daily grind. It won't be as dramatic a challenge as some of the epic travails you dealt with in March, but in my opinion it will be just as heroic.

so where does that leave me?
Perhaps by making these decisions, and closing some of these doors, metaphorically, I will be giving myself the space and opportunity to be open to something new.
Or maybe I am just a total flake.

I haven't quite figured out which is true.
