Honestly, I don't have much personal time now that I am so busy with my 19 months old toddler. I tried to use it to the fullest. I set aside a schedule with what I would do during my boy's hour long schedule. Most of the time is devoted to household chores.
But if I have some extra time before he wakes up, I would take a few moment relaxing in front of my laptop doing some fun girl quizzes on Quibblo. Some of the questions are hilarious and they do help me to unstress a bit.
