The end magical result is more stable, and the waters less troubled if you can do this well. The opposite is true if you expend too much energy to rush the manifestation of an end goal.
However, both expediency and correct action need be balanced in order to get what you’re after. I would suggest that you try to ascertain the maximum amount of change that can be achieved in a given period. Aim just slightly beyond that with your works, and then when you’ve achieved that extreme of development, work backwards to stabilize your results and increase your hold. You’ll thank me. ;)
Have a wonderful weekend,
