There are many jobs that people think may be ideal. Some people say, "I want to earn a lot of money", others say "money isn't important to me, I just want a job that I love". While these two ways of thinking are very common, as scientists, we must truly love our jobs. If we think about someone like Rosalind Franklin, in her studies, including discovering the structure of DNA, she ultimately forfeited her life. Following her death, her fellow scientists won the Nobel Prize for their discovery. In a time when scientists weren't paid well, she could have only done this for the love of her work.

There are many ideal jobs that people dream about. Some people says "I want to earn a lot of money", others says "(MONEY ISN'T IMPORTANT TO) me, I just want to do (A) job I love" generally. Of course, these two (WAYS OF) thinking are crucial however if we mention about being (A) scientist, we have one way: We must love our jobs. Now, we think about (A)scientist who lived in the past such as Rosalin Franklin. (W)hen (SHE) tr(IED) to study DNA forms, she died (FROM) DNA mutation. Afterwards th(OSE IN THE) team research(ING) DNA discovered DNA and they won the Nobel Prize. So she has a(N) ironic story. If she didn't love her job, she (WOULD HAVE) give(N) up and maybe she (WOULD)n't (HAVE) die(D) for this. In the past scientific jobs (WEREN'T) easy, you see. Now if we look, research (IS) more simple than (IN THE) past as we have develop(ED) technology. What's important here (IS) that researchers conduct well-designed experiment(S). Hi, I have made some corrections using capital letters and brackets to highlight them. Some words have been deleted as they are unnecessary. This forum is not designed for reviewing scripts so it is difficult to highlight edits. But I hope this helps.

I get it now, people = they and we must use in that way, thank you Andrew. Greetings!

People is a plural word, so you should change the verb "to say," so that it reads in the "they," form of the verb, not in the third person. So "some people say," "other people say," not "some people says," or "other people says."
