What is the best way to increase our patience?
Meet inactive and dull people. If there are projects which you have to handle and your co-workers are lazy, stick to them. Work with them and allow them to play a major role. You just supervise their routines. Let them put all the efforts which definitely is going to be at a snail pace.
This may affect your productivity since you both are jointly responsible for the project but your objective here is to increase your patience levels. These experiments are necessary to test your patience.
