I am more impressed by those who turn inward and self explore, than those who run around the world searching for something they will never find.
Inner exploration is a far more rewarding journey and costs nothing.
I find it really hard to find good poetry, but when you do, it will transport you to another realm of existence, and take you on an inward journey to magical places.
Music most commonly transports the mind to new places, discovering new emotions and ideas. Good music, different for everyone, can take you on an inward journey.
Meditation will take time, but cost nothing, and can open your mind to new possibilities. The development of new ideas and ways of thinking can come about from meditation and visualization. Take some time to practice.
Personally I have seen great visions through a nightly meditation before sleep.
