Find a comfortable spot and practice the following visualization. Breath in and out in equal times. Exhale from your mouth and inhale from your nose. Every time you exhale imagine you let go of the past, like a load leaving your body, freeing up space. Every time you inhale imagine you breath in the future. Opening up yourself to the new, the exploring, the challenge of the unknown. Repeat the process for a couple of minutes or until you feel ok with it.
For those clung to the past this can help them appreciate the now and look forward to the future. For those fearful of leaping ahead it can increase courage and confidence.
Repeat the visualization when you feel yourself backtracking or simply unable to move ahead.
The mechanics of this exercise are based on the fact that regarding our personal development there is no future and no past. There is only now. At any moment we are able to turn things around, leap forward and escape our mental prison however strong the constrains are.
Try it out a few times and see the results for yourself.
