Don't get bogged down speculating on how something will come about. Instead, get started on what you believe is the best approach at the time, and follow the path wherever it might lead.
When traveling along a road, we never see the entire path lying ahead, but that doesn't really matter. What does matter is successfully making our way through the section of the road that is right in front of us.
Work through the things that must be done immediately, and you'll put you'll be in position to handle the challenges that come along later. Journey down this section of the road, and you'll then be able to travel the next section, and the next.
If you put all your energy into worrying about every detail of how to reach an objective, you will never get started! Instead, remind yourself why you have chosen this path, and then do whatever it takes to complete the task.
You'll never know precisely how something is to be done until you actually do it. So go ahead, get started and discover your own unique journey to success.
