It is possible to build tall buildings through the use of scaffolds—temporary structures that allow workers to climb up to where the building is not yet built. Most great ambitions require some sort of similar structure to allow the creation of something new.
What temporary structures aid you in building toward your goals?
Perhaps somewhat irrelevant because it is not temporary, I suppose,, the current structures that I use to help me work to or from what I see as my current goals or way of life toward death, is the world wide web and all of its attachments. I find that since it is THERE, I resort to it quite often to advance my understanding of something that relates to my goals or to verify that my thoughts about something are wrong (for me).
