I have a quick suggestion for you. Eliminate the ugliest four-letter word from your vocabulary. Do you know what the ugliest four-letter word is? “CAN’T.”
When you repeat a word or a phrase over and over and over, you know what happens? A belief is formed. Beliefs can be positive and negative and they become a filter by which you screen your world. In other words, once you have a belief accepted as “truth and reality” you begin to filter your work accordingly.
