Some people get very offended by particular four letter words. Others use them so much that they cease to have any power whatsoever. Despite their semi-taboo nature, the things that they represent are quite common place. The teeth of the matter can be taken out by substituting a word. It’s the word that makes it vulgar and repellent.
By contrast, the word “DO” has almost no connotation whatsoever. It shows up in so many contexts that its meaning is somewhat of an afterthought. When it’s not holding up space at the beginning of a question, do implies some form of action. Therein lies the problem with this seemingly insignificant word. People are not afraid of the word, they’re afraid of what it represents. ACTION that will take them out of their comfort zone or cause them to face their inadequacies. Do may only have half the characters of the four letter words but it has ten times the bite. People are paralyzed by their do’s.
So just like the foul mouthed people who drop the F bomb way too much, the key to reducing the potency of something is to increase the frequency. DO until you’re not afraid to do anymore. Give it a shot! Try! (That’s right Yoda, I said TRY! Go F#%$ yourself.) Succeeding/Failing do not matter anywhere near as much as the feeling that you have about who you are when you unshackle yourself from fear.
