Develop a tolerant attitude toward the habits and idiosyncrasies of others. Otherwise, you'll find yourself constantly annoyed by others.

Try to turn the potential annoyance into something positive. For example, if you are attending a class and someone frequently asks irrelevant questions, don't become annoyed. Rather, view each question as an opportunity to help you build up your "tolerance muscles!"

Today, catch yourself getting annoyed by something, and consciously use it to develop your level of patience.
