My mom has said this thousands of times in my life. Whenever i say "I'm bored" she replies with "only boring people get bored" and im just realizing how true that is. When you keep busy, keep not boring, you don't get bored.
Yes life is too short to live without true happiness and purpose. Therefore, it should be our mission to seek out the truth about Jehovah's Kingdom. Knowing the truth and being a faithful servant of God brings peace now and forever!
