Some call it a goal. Whatever you want to call it, ultimately you must take some kind of action if you really want to achieve it.
Choose which dream you want to go after and give it everything you've got. Chase your dream. Be like a long-distance runner and chase it down until you catch it.
Chasing it down means planning a campaign to achieve it.
Just in pursuing it, working toward it, chasing it down will give you a certain amount of satisfaction. Achieving it is the cherry on top of the ice cream sundae.
I love what Charles Kingsley once said. "We act as though comfort and luxury were the chief requirements of life, when all that we need to make us happy is something to be enthusiastic about."
Burn with enthusiasm. Chase your dream. When you capture it, expand your horizons and find a new dream.
