In this life, there are many shiny things along the journey that drag us to the wrong direction. We may move slowly towards our dreams when we are dabbling in many things.
To be really successful in this life journey, we should focus on one thing at a time. FOCUS on things that matter that you can control.
FOCUS all your strengths and energy doing what you are good at that make you happy and make other’s life better. FOCUS on core competencies and hire the rest out. Focusing lets you become an expert.
