I'm a big believer in growth. Life is not about achievement, it's about learning and growth, and developing qualities like compassion, patience, perseverance, love, and joy, and so forth. And so if that is the case, then I think our goals should include something which stretches us.
Being in business is all about learning and growth. We grow when we fail and grow when we succeed. Every day in business is a day to learn something new. Keeping up to date in business stretches you when you set stretch goals.
