I think sometimes people think that with time POOF things will just be perfect and that everything will be right with the world and so they live by that thought process to give them hope for a better future. I don't know.
Being proactive, working hard, pushing past obstacles, getting out of your comfort zone, and setting short term and long term goals to meet. It is true that I cannot do all those things all in one night, but just waiting for time to pass won't make anything better. I understand what you are saying, and unfortunately I can't (no not can't..I won't) fully voice my opinion on sayings such as "it gets better with time" because I am sure it will anger many people and that would not have any time of positive outcome.
