Having A Big Dream
There's an old saying, "If your reality begins with your dreams, your dreams will become your reality." And the point is that, if everyday you wake, and work towards your dreams, then soon enough your dreams will be achieved and become your reality.
Having big dreams is what makes the journey of life worth it. When you ask little children - "What do you want to become when you grow up?" They'd tell you things like, "I want to become a doctor." Or "I want to become an engineer." Or "I want to become a pilot." And so on.
There's probably no child on Earth, who will reply to that question, saying that they want to become a loser in the future. This means that even from childhood, the thing that makes life worth living, is your big dreams that you want to achieve.
And the truth is that, it's much better to have a very wild dream, that seem unrealistic to most people; than to have no dreams at all. Having a big dream for your future - is what gives you the strength and the courage needed to achieve daily tasks.
