To be committed means “to be dedicated to a task or a purpose”. All great achievers both living or long gone have in one way and another stayed truly committed to what they did. You can also be like them!
You don’t waste your time jumping from one task to task to see yourself as a master in a particular task if that’s not the purpose of God for your life. That is called inconsistency. Rolling stone, I heard someone said, gathers no moss. By often falling on the same spot, the rain makes holes in the rock. Just stay true. Be committed to your purpose and consistent in your goals and you will become the very person you dedicated yourself to become.
