The trick is pre-planning. When you commit to events with groups, the desire to not let anyone down overrules all else. Then you realize you have fun anyway!

Most of my weekends are already assigned and I purposely allow for some rest days. And I usually allow for some spontaneous requests to hang out.

I'm happier than I've ever been and I know more people now than I've ever known.

You still need time to yourself so you should respect that but knowing that these people care about me is nice :)
