How does having "ample time" coincide with a schedule?

I have a negative belief pattern that I don’t have enough time. This underlying thought causes me to stress when my daughter needs me and I snap at her.

C – Daughter needs my attention
T – I don’t have time
F – Anxious
A – Snap at her
R – Regret

I’m thinking about the intentional model where my underlying thought would be “I have ample time” and my actions would follow that I behave in a manner that welcomes her and demonstrates my love for her, in place of the anger I so often feel.

But I cannot imagine this reality… If I behave as though I have all the time in the world, what about my schedule that will inevitably get pushed?

Thank you.
