I'm a busy mother of three, grandmother of one and a daughter in law on the way (in less than a month and a half). So having free time seems to be a thing of the past. Don't get me wrong I love every minute of it. I do know if they made juggling an Olympic sport, mothers and fathers across America would have gold metals.
I think you need to learn and I say learn, because if you are like me I do have a hard time with this part. You need to learn to take time for yourself, it will make you rejuvenated and ready to start a new day with your loved ones.
For me it's reading, and gardening. I get a thrill out of each project I undertake. Seeing what my gardens will look like once they are done.
