this question makes me think that you have already been thinking a lot about being a scientist!
For me there is one word that represents my attitude with work: honesty.
It could be tempting to modify some data so that you can get published more easily, but once you do that, I think morally as a scientist you are destroyed!
I think the most important quality in a scientist is curiosity. I don’t think it’s possible to be a good scientist without being fascinated by why the world is how it is!
Morally, I think the most important thing is to be honest – as lying about your research can do a lot of harm! Other than that, I think scientists should try to live by the same morals as everyone else – don’t kill people, don’t steal (especially other people’s work) and try to think of how your behaviour and your science will affect other people.
– Open minded
– Hard working
– Willing to perservere
– Self confident
and have a strong set of ethics. Science ethics (which, I suppose, brings morality to science) is extremely important, and a scientist should never ever be dishonest, or corrupt, or conduct experiments in such a way which causes unecessary suffering, and should always go through all the right procedures to ensure that their work is ethically sound.
