Problems Completing Tasks

I've always had a problem getting things done when I'm under stress or overwhelmed. The critical tasks all get done. Deadlines that need to get met are met, but other things will begin to fall off the table. Even things that are important in the medium to long term.

Take billing/invoicing for example. I just need to do some hours totals and put together the invoices, but it seems completely overwhelming so I put it off. I can't seem to muster the focus.

And it's not like I don't need the money. But it won't kill me today, and it won't kill me tomorrow, or even this month. So I end up sluffing it. Too many things on the plate. Too much running through my mind.

I prefer one or two items that I can focus in on and take apart and reassemble.

Too much stuff all at once rattles me. That, in fact, is usually the source of any times I blow up at my kids. When they ask me to do too many things all at once and there is no way I can meet all the demands I lose it and get angry.

I imagine that part of it is just learning to say no. Learning to refuse more than I can actually handle.
