You should join scouts or try camping! They are fueled for adventure and go all around the wild and the world, doing new things and learning life-long important skills! You could also play video games, but that might not be the experience you're after.
For me personally, this might not help you I'm not sure, you can find such excite from learning about the universe.
Let me give you an example.
Right now, in your body, you are made of particles known as atoms. The amount of atoms in your body is substantial, there are quite possibly more atoms in your body than stars in the Milky Way. Each individual atom is made up of nucleus of clumped together positive protons and neutrons (with no charge), around this nucleus is whirling around electrons. Right from there, we can look back and say that, that's pretty amazing, think about it, what defines you as a person involves trillions of tiny electric bolts moving at super fast speeds spinning around an impossibly small radius.
But that's only one thing, the nucleus of the atom is also quite spectacular. It was discovered by a guy called Rutherford who literally (and yes this is the scientific word) bombarded gold with alpha radiation. Imagine it like a wall of large balls being shot by billions of little pellets at high speed (Gold atoms being hit by helium nucleus's (alpha particles). As a quick side note, most of particle physics involved hitting two things together at really high speed, how do you think we may of found the Higgs Boson? We got a proton and a anti-proton (Another cool thing about antimatter is when matter and antimatter come together, they hit each other and (another scientific description) annihilate each other creating substantial amounts of energy) and then whacked them together at 7 TeV (That's about the same energy of a fly hitting your shoulder, now think that a single particle can have that much energy). Anyway, so back to Rutherford, he discovered through the deflection of the bombarding alpha particles, that the nucleus is about 99.99999% smaller than an atom. So if we were to say an atom was as big as a football stadium, the nucleus would be a grain of dust. So by comparison that means that you're 99.999999% empty space (because the atoms in your body are 99.999999% empty space).
So that's great, but what about the nucleus. WELL, the nucleus is made of protons and neutrons, we won't worry about the neutrons so much (although you should look them up, they're responsible for fission and the nuclear bomb). So anyway, protons have a positive charge of +1, now you may recall that like charges go apart. If you think about a magnet, (oh yeah, electricity and magnetism are actually kind of the same thing, whenever you have electricity you have magnetism and vice versa) if you put two "north" sides of the magnets together, they will repulse. If you put two positive charges together, they will also repulse and try and get away from each other. Now if you think about the nucleus of an atom, lets say the atom is helium, we have two protons in the nucleus. These protons are in a space so close to each other (a spec of dust in a football stadium of an atom, which there are more atoms in your body than stars in the galaxy) they are trying to get away from each other REALLY REALLY BAD. The force is so strong that gravit, has absolutely no significant effect on these charges, the repulsion of these charges just absolutely dwarfs the attraction of gravity. So, a force that holds these particles together is known as the "strong nuclear force" or just, strong force. It's called strong force because it's very, very strong. It holds these particles together into the nucleus with such strength that even the overwhelming repulsion of the protons can't beat the strong forces attraction. Now, the strong force only works in very short distances, smaller than an atom, but at these distances it is very powerful.
So, a small summary. What we've learned today is that you are made of billions of tiny spinning electric charges, you are 99.99999% empty space and your atoms are under a constant battle between the forces. I think that's pretty amazing and exciting.
