Remind yourself that things take time.

"People who are impatient are people who insist on getting things done now and don't like to waste time. However, some things just can't be rushed. Think about your happiest memories. Chances are, they were instances when your patience paid off, like when you worked steadily towards a goal that wasn't immediately gratifying, or took a little extra time to spend leisurely with a loved one. Would you have those memories if you had been impatient? Probably not. Almost anything really good in life takes time and dedication, and if you're impatient, you're more likely to give up on relationships, goals, and other things that are important to you. Good things may not always come to those who wait, but most good things that do come don't come right away."
