… As a scientist, you are a professional writer. Writing is as important a tool in your toolbox as molecular biology, chemical analysis, statistics, or other purely “scientific” tools. Some of these tools allow us to generate data; others to analyze and communicate results. Writing is the most important of the latter. Because it forms the bridge to your audience, it can act as the rate-limiting step that constrains the effectiveness of all other tools.—Joshua Schimel [1] Science requires communicating new and exciting findings to diverse audiences. Written communication is especially critical for our success as scientists because we must write to receive degrees (e.g., dissertations), share our discoveries (e.g., manuscripts and abstracts for professional meetings), request funding (e.g., grants, contracts), etc. The process of writing can also refine our research because good writing is an iterative process, with feedback leading to new ideas and experimental follow-up. In reality, we often postpone working on communication until we feel ready or a deadline is imminent, which diminishes our ability for clear writing. We often procrastinate sharing our writing because we consider our audience to be only the peer reviewers of grants and manuscripts. We neglect the opportunity to use perhaps the most important audience of all: ourselves. The best way to engage with ourselves is to develop a strong and sustained writing practice. Writing every day, even for a short time, improves our thinking and our productivity as scientists. It provides time and space for reflection, allowing new ideas to mature, and maintains perspective on challenging work. We agree with Scott Montgomery that “… ‘clear thinking can emerge from clear writing.’ Imposing order by organizing and expressing ideas has great power to clarify. In many cases, writing is the process through which scientists come to understand the real form and implications of their work” [2]. However, even with the best of intentions, it is easy to postpone writing (Box 1). We believe that establishing a writing practice must be a deliberate act. We further believe that the pay-off for establishing this practice will be found in increased productivity and impact. Here, we outline 10 simple rules for improving your writing productivity, which will also enhance your thinking as a scientist. Box 1. Hurdles to writing that all scientists can face Types of Writing Resistance Evaluation: “This draft stinks.” Inspiration: “I don’t have a good idea yet.” Motivation: “I just don’t feel like it.” Optimization: “I need to make this sentence perfect.” Procrastination: “I will start working on it tomorrow.” Separation: “I need a lot of time in a quiet place to write.” Temptation: “My lab bench is really disorganized; it needs to be cleaned now.” Rule 1: Define your writing time The essential key for writing is to write regularly—like it or not—great ideas come often by writing; releasing the subconscious—waiting for inspiration and ideas will not work, but it does help to have a notebook with you all the time for sudden brainstorms or inspiration.—Dr. Robert Marc Friedman [3] Commit yourself to writing daily or at least three to four times per week by defining the time when you will write. Pick a bitesize chunk of time where you are unlikely to have conflicts, so that this time is protected for writing and nothing else. For example, if writing right before bed results in a conflict with exhaustion, choose a time earlier in the day. Setting aside just 15 to 30 minutes each day may be sufficient because even short amounts of time can enable meaningful increases in your productivity. As you set your initial goal, consider the SMART criteria: specific, measurable, action-oriented, reasonable, time-bound [4]. For example: “I am going to write from 8:30 AM to 9:30 AM on weekdays.” Write down your goal on a sticky note, and place it where you will have a daily reminder of your goal—attach it to your coffee grinder or stick it on your computer screen or near your pipettes. Block off the time on your calendar as another permanent reminder of your commitment to writing. You might also use a calendar reminder or an alarm on your phone to catch your attention when it is time to start writing. Then, when you are more comfortable with your writing schedule, consider building up the time you spend writing.
