A counceler said this to me several years ago. Which one takes more work and effort and which one keeps you stuck, and drains you of joy and wastes your time leading to regret? To be bitter, self loathing and depressed? Or to be striving forward, positive and independent? Remember there are two things certain if life. Death, and taxes, and even the second one is optional. The only thing that is constant is change.. Hold your thoughts captive. Im very guilty of this too. If you feel yours self going negative. Either imagine a stop sign, or observe the thoughts, write them down, and ask yourself. I this really serving me?
