"Always focus on what you want rather than what you don't want." How do you describe this statement.​

i say its telling us that we should always focus on things that we feel are special to us and not whats special to others

Explanation:

so for example i want strawberry cake but my friend wants chocolate and since i desire strawberry im going to get it because im focused on it

i don't really know the circumstances. i personally think not due to it not being fair for all parties and how hated i'd become if i thought it was a good thing.
