Yes, you could, but what is the relevance of that belief? There will always be an excuse, an inner voice suggesting negative beliefs, if you don't genuinely want to give up smoking. The comment above is just one example of the beliefs that smokers might have. Yes, you might be run over tomorrow by a bus, or die suddenly in some other bizarre way, but you probably won't. Whereas if you stop smoking you are likely to live a longer and better life.
You may wish to question beliefs which harm you – confront them and override them. Ask yourself directly if you really think you'll get run over tomorrow. The answer will probably be “no”.
