It's simple. You lack passion for the market. If you were in love with a girl you're seeing, would you just walk out on her in the middle of conversation? No, you would take interest in everything she does, in every word she utters, in every movement she makes. If you don't find interest in her, then it means you don't find her attractive. It's the same thing with the market. If you were passionate, you will find meaning in all its moves. Why was it that this candle is above the previous candle? What's up with the lagging volume when it "should" be doing otherwise? Etc, etc. Questions and answers should be swirling through your head.
However, if you can't focus on trading and rather prefer on doing something else, maybe this isn't right for you. You should move on and find something more meaningful, something that you're REALLY passionate about. Forget about money and listen to your heart.
