"Haste makes waste" says that when we act too quickly ("haste") we are more likely to make mistakes and end up with poor results ("waste"). Example: "Most spelling mistakes are the result of going too fast and not checking your work; haste makes waste." "Haste makes waste" also says that it is better to do things carefully than to do them quickly and carelessly. Example: "I want you kids to take your time doing your homework tonight; haste makes waste!" The results that we end up with when we do things carelessly are often useless and sometimes costly. Example: "You should always take your time when doing your taxes and check your numbers very carefully; haste makes waste."
