Actually life isn't up and down, the motion we experience is in the way we perceive what life throws our way.
That roller coaster ride in the gut can be a good thing.
We are adapting and changing and growing every day. Every minute.
Sometimes we don't like the circumstances, but how we deal with changes helps us mature and advance. The teeter totter ride is up and down, and at least some of the time we are riding even and in balance. Time to catch your breath and hang on for the rest of the ride.
At least that's how I see it. I will be the first to admit that I am womanly, an adult female. But I have so much to learn.
Most of the time I enjoy the ride.
