1. Dig it, seriously. I guarantee that it will excite your PI or colleagues if you are genuinely interested in what you are doing. Plus, it makes it 10x more fun for you.
2. Why>>>>What. Always. Understanding why you are doing what you are doing is critical; it is what makes research what it is. Why you are doing it at that second, why you are doing a task in terms of your project, why and how a project fits into the long scheme of the lab. If you understand why you are doing something, you know what to do once you see the results. 90% of pre-med researchers don't get this and get stuck going through the motions and doing "b*tch work" everyday. I do "b*tch work" everyday; run gels, PCR, grow cells, etc.--but understanding why you are doing it and how it fits in ultimately doesnt make it "b*tch work" anymore. Working to understand this will immediately put you ahead of the curve.
3. Publishing is overrated. Don't think about it early on; it will just ruin your expectations and misguide your goals.
4. I guess I disagree with the above posters; basic science research is f-in sweet.
5. Repeat 1. If you can't, then move on. Your specific area of research or research as a whole might not be for you, and staying around just drags you down.
