Two of the simplest, but for me most effective writing tips are:
1) Avoid “this”, or “it” as much as possible. And if you use either of them, make clear what you mean.
Example.
After you added half of the chocolate to the dough set it aside to let it warm up.
So what should I set aside the chocolate or the dough? This is really hard.
Wait a minute. What is hard? Baking or writing?
Yes, I watered your plant with the watering can, but it had lost some parts.
What do you mean some pieces, leaves? Did you ruin my plant or my watering can?
I borrowed your laptop and your favorite book. You know I dropped it by pure accident.
What?
So I guess you get the problem. Be precise and don’t leave the reader wondering what you mean unless you do it on purpose.
2) Use as few adverbs as possible
Instead of using adverbs use better fitting verbs
She ran quickly down the stairs becomes she flew down the stairs.
He walked very slowly towards the corner of the house becomes he inched towards the corner of the house.
See my point? Replacing adverbs with stronger verbs makes the writing more visual.
Happy writing!
