Uncertainty

Why is there fear of uncertainty? Is it because there is desire for certainty? I have been chasing after this and that all these years ... and when I say I want to be at peace with myself and all around me like where I am now, I'm still chasing, isn't it? When I draw a house together with mountains and a river on an A4, the location of the house is up on the mountains overlooking the river, which to me represents peace and serenity. Well, I am a city person and I can't live in the mountains. The point is this: When I was drawing, I did not picture myself already in the house, overlooking the river but as something to look forward to. Although I am in peace now, there is still much more to do, to achieve, with family, work, everything else. There you go ... I'm chasing. After what? Isn't it true that uncertainty is the only certainty?
