If you wanna go from New Delhi to Mumbai via road, you do not need to know the entire route. You just need to put on the navigation and start driving.
If you wanna go from point A to point X in your life, you do not need to know the entire way.
You just need to decide.
The way will be shown to you as you make the leap from point A to B.
The right question to ask is: “Are you willing to start?”
