How much should I invest in my further education?
Sometimes your employer will fund, or partly fund, your desired professional development - but even if they don't, it's still an important factor to consider. When trying to decide what to invest in, draw up a plan highlighting where you want to go, and your own existing strengths and weaknesses. Be honest with yourself. You may find that you can develop experience in some of these fields through refocusing your attentions in your existing work or study - be sure that you document this kind of unofficial education so that you can easily demonstrate it in the future.
How can you absorb your reader into a descriptive piece of writing?
Include words that appeal to multiple senses, so the reader can easily imagine themselves in the situation being described.
What is the most important factor to consider when drafting a professional written communication?
Tone - remember that each person reading the communication will have a different perspective and overlay their personal values onto the writing - tone must be firm, yet neutral, to avoid being interpreted as aggressive, controlling, or passive aggressive.
