I always advise junior researchers, at the early stages, to (1) employ, refine, and improve their skills by participating in several small, pilot, initial research projects rather than doing a high-impact, high-quality, mega project, (2) get involved in multiple research projects as long as they can, and (3) accept the risks of doing mistakes and the risks that some projects might eventually be published in modest journals. My advice is always criticized by people who advocate the "Quality NOT Quantity" thing. In this post, I explain philosophically, scientifically, and historically from my experience, why the "Quality NOT Quantity" mindset does more harm than good for early junior researchers (0-4 years).
In the following paragraphs, I summarize the key phases of my research journey starting from July 2014 until now.
1- First, you should do research to learn (phase I), then to become motivated to do more (phase II), then to become personally satisfied (phase III), and finally to advance science and improve your field for the remaining of your academic career.
2- Participate in as many research as you can, provided that you are not doing 3 things: (1) Ethical misconducts, (2) Plaigarism, and (3) Publishing in predatory journals.
