No one wants to go through life in a conglomeration or regrets, unfulfilled dreams, and muddled half-ideas. Having no specific task is a setup for failure. Setting goals keeps you focused on a single task at a time.
There are two types of goals—short term and long term—both of which are quintessential to a productive life. Long term goals give people more motivation to get where they want to be in life. Short term goals help to achieve long term goals. Goals can be as simple as passing a math test to [becoming the] CEO of a major corporation. Goals help to finish projects on time. When I was building a model fish, I set daily goals of what to get done. By building it piece by piece each part was detailed, and when they were put together each piece made the model greater. If the model was done as a whole, less attention to detail would be made and the project may not have gotten done in time.
One long-term goal might be to learn how to ride a skateboard and perform tricks. Trying to learn how to ride a skateboard and new tricks would be frustrating and near impossible. But if you break it up into several smaller goals the whole experience becomes less stressful. By becoming proficient in riding the board and only then learning tricks the goal becomes more manageable.
Setting goals keeps you focused on a single task at a time. This makes achieving dreams within reach. Many achievements could never be made without goals.
