From the moment an action starts, time and energy are invested. Money may or may not be a part of it. It depends on the action. As we do the action, procedures are taking place. Externally and internally. What we’ll see as profit and what we’ll see as cost, is subjective. For example, putting energy and time to writing. What do we take back? Feedback, interactions, connection, realizations about ourselves(possibly), and maybe money. Now, how much value do we give to each one of these, depends on us.
Subjectivity is also a factor because, every action has a reaction. I write-something comes back. Internally and externally. What is enough for me and what is not, is subjective.
(Did I make my point clearer, or more fuzzy? I wonder) : -P
