All journeys, all lessons, everything in life begins with the first step, the first decision, the first thought, hope, realisation.
It may seem impossibly hard, when looking at it from this side, as if it is insurmountable, ludicrous, beyond our capabilities, but that is when we look at the top of the mountain from the bottom. It seems, and is, such a long way away, such a difficult journey, so many obstacles to overcome, but when we do not look to the top of the mountain, but look only at the step just in front of us, it is suddenly so easy, so attainable.

There is no need to scare ourselves by trying to look into the future or wishing ourselves already there. There is but a composite of each and every step we take towards it, so as long as we begin, and take that first step, then we are on the path and that is all that matters.
We would not want to wish ourselves to the top, and miss the flowers on the hillside on the way up, the scampering hares or varied views. So long as we keep putting one foot in front of the other, even if our pace is slow, we will eventually reach the top and we will have both the experience of the journey and the sense of personal achievement with us.
Focus only on what you are doing now and the rest will come. Begin.
