I do know how you feel. I think we've all gone through lamenting that there simply is no time to do the things we say we'd like to.
With two kids with autism, a very busy teenager, and a husband who travels extensively with his work, I thought I'd never find the time to....write a novel, exercise, cook healthy. Clean under my bed *g*.
When I came to terms with the fact (with a little help from my DH and yes, I wanted to strangle him when he said it,) that I wasn't doing all of those things because I chose not to accommodate for them in my life, I found creative ways to add the things I kept saying I really wanted to my life. That is, I found the time after I got done ranting about all the reasons I couldn't do those things. :)
The time I used to spend vegged out in front of the tv is now spent on my elliptical watching DVD's of my favorite series or movies I've wanted to see. If I haven't done my exercise, those shows don't get watched.
My husband put a nursery monitor in every room so I could keep an eye on my sons and still be free to cook healthy meals. I write when my kids are asleep. Granted, it's still a mess under my bed :)
I take my laptop out to the pool now so that while my kids swim, I can work on my writing. All the time I spend waiting in cars to pick up my kids, I now spend dictating stories into my handheld voice recorder.
Since I agreed to actively rearrange my life to accommodate for some of my dreams without sacrificing my family's needs, it became doable. I left the 200 pound mark behind several months ago. I sold a novella a couple of months ago to a respected publisher and have another going to contract in the next couple of weeks.
I know it sounds awful to put in writing, but every day brings with us a set of choices. When we make a new choice, we change how the people in our lives respond to us, and that, in turn, changes how we view ourselves.
There is room in all of our lives for dreams. I truly believe that. I choose to be happy, fulfilled and healthy. By doing that, I am a far more effective mother, teacher, and advocate for my children, and a better wife to my husband.
And I'm so happy to have Alli as a little extra support in a frantic life!
