This question isn’t for people who are still daydreaming about starting a business, finding a spouse or getting out of a tough spot in life. Feel free to skip it if you are still daydreaming.
It’s for people who are actually in the throes of taking action, and still second guessing themselves.
To be interested means that enthusiasm got you to start that business, get married or attend therapy. To be committed is a totally different ballgame. It means doing whatever it takes to stay in business, stay married or complete the process of ridding yourself of that tough spot you found yourself in. It’s a question you must answer for yourself, sincerely.
