One day it occurred to me, what if I just chose one thing to work on for 15 minutes a day until it became a habit? So I started with walking, just going out for a 15 minute stroll after I dropped the kids off at school. I even took my phone so I could time myself. Sometimes if the weather isn't good I will just walk in place for 15 minutes, or maybe just stretch, as long as it's 15 minutes of exercise.
You could do this with anything: play with your kids for 15 minutes, throw the Frisbee to the dog, check your email, meditate, clear clutter. I tend to be an all or nothing kind of person, I either do it all the way or not at all. So this is a good way to start to find the balance for me. Especially if you are feeling anxious about making a change, doing it slowly at first can relieve some of the stress.
Get out a notebook and write down all the things you would like to work on, cross them off as you accomplish them. Another thing that I found helpful, was letting go of all those projects I've been meaning to get to. They had been in my attic for years and every time I looked at them I felt overwhelmed and like a failure, so we sold them at a tag sale and I felt really good about it. If I didn't get to them before I had kids and a house I'm certainly not going to get to them now, LOL! Sometimes a girl just needs a bit of a fresh start.
So why not set a timer for 15 minutes and see where it leads you.
