Take this for example, right after Nathan graduated from college he was hired at an accounting firm with great benefits, generous salary and amazing people. He loved his job but soon after realized that there was no where for him to advance in the company. He started thinking, how am I going to grow as a person if I can't grow in the company? After much contemplation, he decided the only way to bigger and better things was to quit. He didn't want to go marching into his boss's office, a proud college graduate now being deemed a "quitter". He didn't want to let everyone else down at the firm but it was the only way he could see out, so he quit. It wasn't fun and it definitely wasn't easy, in fact he was scared out of his mind. Nathan soon after returned to school, furthered his education and now owns and operates a very successful and growing accounting firm. All because he knew when to quit!
I'm not saying yes YOU go quit your job right now, but think definitely about it. Does it make sense? Will it lead you to where you want to go? Maybe it's just a transition. If not then perhaps you need to think about a "quitting strategy" to get you where you need to be. You can apply this to all different aspects of your life. You can quit all kinds of things like eating junk food, smoking, being lazy, or having a poor attitude. In the words of Seth Godin,
Now get out there and start quitting!!
"Quit the wrong stuff. Stick with the right stuff. Have the guts to do one or the other."
