Just wondering - is this an excuse?

As a mom, my time is divided into small chunks of "free" time. Small, I mean between 3 to 10 minutes small. And by free I mean uninterrupted time by some solicitation that begins with "Mommyyyyy?"

If I think better at this, I have the luxury of 30' sometimes, even 1 hour. BUT (of course, there is always a "but") I never know when this luxury will happen. It's really unpredictable. As long as I am home with my amazing daughter, I am at her disposal. Personal choice, as we have only a few hours a day together. Sometimes she plays by herself, or with the kids from the neighbourhood, not needing my "assistance".

Where am I going with this?
I was just wondering... I always said to my self that I can't start writing/reading/learning/working something (for my business) if I don't know for sure that I have at least 30' uninterrupted time to focus.
So I don't do it. And I find myself wondering through the house, not doing anything actually. Just wasting time, not finding my place, waiting for the next "mommyyyy" to call me, wishing I would write/read something, longing to do that, feeling anxious, but not doing it. Cause I'm waiting...
Ok, sometimes, to feel useful around the house, I put some clothes/toys back to their place :))

And just now, as it's night and we are preparing for bed - well, we should be preparing for bed, but my daughter still has to play some more - I was wondering, what IF all this is just an excuse?!? What if I saw it as an excuse, and when I feel like it, like I have 2 minutes, I would just start writing/reading/learning? What if I could train myself to function this way? To get the most of the 2 minutes?

Yeah, I know the theory, that if we get interrupted, we need at least 10-15 minutes to get back in the flow. But what if it doesn't have to be like that? What if I use that time, and I get interrupted, and I start again and focus, and then again and again? And I use neuroplasticity - my brains capability to build new neuronal paths that would actually allow me to get right back on track?
Can you imagine how much progress I could make? And how my heart would be satisfied and happy that I am doing something I want/love/enjoy?

Wow, I can really imagine that! And it's amazing that only today it hit me, this wondering :)

And I am realising that this is about limiting beliefs that I accepted as a fact ("studies show that it takes 10 to 15 minutes to get focused again..."); and it's about perspective - looking at this from another angle, and about choice. What if this is just an excuse? What if I could look at this and some other beliefs I have, and maybe challenge them this way? I am wondering... and not just wondering, but I have already started doing this, like right now, while wondering :))
I choose to get out of this limiting belief, I choose to find a way to enjoy every precious moment, and I choose to experiment.

P.S. I wrote this in about 15 minutes, while being 3 times interrupted by my lovely daughter. So yeah, I am on the right track here :)
