In need of an antidote for busyness!

Starting Wednesday, our family's life is going to get seriously busy.

Usually we have a maximum of 2-3 activities slated on the week's agenda.  But soon, we'll have commitments almost every single day for the next week and a half.

I'm getting edgy and nervous as to how this added busyness is going to shake out.  Besides affecting me adversely, I know it's also bound to make for crabby attitudes and increased meltdowns in the kids.

Thankfully, most of the activities on the calendar don't include ALL of the family.  A lot of it is falling squarely on me.  Sigh.

I REALLY don't want to transform into monster mommy/scary wife during these busy days.  I know it affects the ENTIRE household when mama is stressed out.

So, here's where I need your help.  How do you keep your spirit and attitude calm when life is going a zillion miles per hour?  I know God is key in the equation here.  I'm already drafting a plan to prioritize some quiet time for reading and praying each day. 

Any other practical tips for maintaining sanity during busy seasons?
