It happens to be our family motto. Seriously.
Suck it up.
And yes it is a bit crude, but you would be surprised at how many times it works as an answer.
Basically, we want to teach the girls (and ourselves) to be a little tougher when needed, complain less often (how much good does it really do you?), and be flexible.
Traveling like we are is certainly different than vacationing, maybe harder in some aspects. It pushes your boundaries and tests your comfort zones. Not every place is going to be the most friendly, have the thickest walls, the most comfortable beds, the softest toilet paper, the coolest air-conditioning (or any for that matter), the fastest internet, or the best coffee.
You then are presented with a choice. You can be unhappy, stubborn, uncomfortable, and unpleasant to be around. You can choose to let the not so great things take over and limit your experiences or you can say it with me: Suck. It. Up.
