February is a time of change for nature.
Sometimes change for humans is unnecessary, like putting a wig on a bald man. Would you put a wig on a bald man because you’re ashamed of what nature and God gave him? If so, that’s not only unnecessary, it’s ungrateful.
For a writer, throwing out a whole chapter for only two spelling errors would be an unnecessary waste of time. Throwing out a whole chapter because it created an awkward transition in the throughline, the plotline, the character growth, could be necessary. Are there any howevers? There are many howevers for you writers out there. Changes come in spurts, but not for you, for your work. Your work may require the change.
Changing your political party would be unnecessary if you were Democrat switching to Republican or Republican swapping to Democrat. They’re both virtually identical. Republicrats.
Changing your underwear is necessary. Make no mistake.
Changing your gender is not likely to be necessary. If your aim is to rob someone, you only need to pretend. A man in Uganda found out his “wife” was a man. The “wife” got caught stealing a television and confessed to faking it so he could rob the “husband”.
Changing your diet may be necessary if you become ill. If you could prevent the illness, would you? Cutting sugar intake to thwart diabetes, cutting coffee to inhibit osteoporosis, cutting out alcohol consumption to defy cirrhosis, hepatitis, pancreatitis, and/or dementia, could help, but a healthy diet and exercise should be something you start with, not something you use as a fall-back mode. Does that mean it’s too late to be healthy? Of course not. What it does mean is you may not reap much benefit from deciding to drink less alcohol after the liver failure.
