Building requires work and planning.
Building a building takes an architect, and blueprints, and construction teams, and hundreds of other things that I don't know about, because I wear glasses and use a computer keyboard, instead of a hardhat and a shovel.
Making a cake takes a recipe (or some plan, at least), ingredients, an oven, and some previous knowledge about baking (don't put the egg shells in, mix it enough or not too much).
Building a relationship takes time, and energy, and sacrifice. Friends don't become friends overnight, and once they get there it's still work.
Making a story means creating characters, formulating plot, setting the stage. It doesn't happen without a fair amount of thinking and planning.
Sports teams don't become champions overnight, an ice rink doesn't freeze in one minute, Rome wasn't built in a day.
Putting the work into building something is worth it. It is an accomplishment, and achievement, an exercise of will. Sometimes there is a reward for completion, but often, finishing is its own reward. It is the ability to step back and say, "I made this," and to recognize that perceived value aside, it is good because you made it.
Build with the value of the finished product in mind. It's worth it.
