Don't know what I can teach, but I can give you some guidance! You should check out the tutorial videos all around here. There are some on the wiki, and there are plenty in the forums. Look at reaching orbit and how to do that well. Orbit around Kerbin is literally halfway to anywhere, as far as Delta-V is concerned. And speaking of that, you should brush up on actual rocket science. It helps a ton to understand Delta-V, specific impulse (ISP), the rocket equation, Thrust-to-weight ratio (TWR). All of those help you build better, more efficient rockets. KSP is designed to act like real life (mostly), so real-life science can help you. If you want the motherlode, check out Nyrath's site. You'll have more info than you know what to do with there. You'll want to learn docking too. It's not just for stations, as you can assemble larger interplanetary craft in orbit. Then go to the Mun or Minmus. Then maybe try Duna or Eve. Think about how NASA grew. Suborbital flights, then orbital, then rendezvous/docking, then the Moon, then other bodies. Don't bite off more than you can chew right away, because you'll get frustrated! :-) Honestly, I've learned by trial and error (lots of explosions!), and then by using MechJeb. MechJeb's an autopilot, so if you like flying on your own, I wouldn't use it. But, it can teach you what a good ascent profile looks like, how to rendezvous with another ship, transferring to another planet/moon, etc. Once you've seen it done a few times, you can do it yourself. It also gives you the important numbers (Delta-V, ISP, TWR) for your ships in the VAB/SPH so you aren't guessing about "Can this reach the mun!?" you actually know. Also, remember, you really want the smallest/lightest vehicle that can do what you're planning. More weight = less travel. On this note, look up asparagus staging. It's the most efficient way to stage, and will help a lot. Ok, that was a bunch of random thoughts, so I hope that helps!
