Will power of attorney suffice for someone to purchase a property in your behalf? 

Usually I am the type of person that has been chronically late, fickle about my interests and goals, prone to procrastination, and generally weak in matters of will power; and I realize that this admission might weaken my chance of working with those who read this should I not succeed in the near future, but I am posting this in part for those who might be or might have been in the same position.

You also need to have the will power and calmness to not freak out as your stock and real estate portfolio value gets cut by half or more.

This is akin to will power & self-discipline, and often plays out in situations around food, exercise, alcohol, studying.
