There are no secrets.
There is no one-way.
The answer is that there is no answer.
So stop looking for secrets, stick with the basics and build on them. Don’t look for one way to do things, equip yourself with a variety of tools and methods. Learn to ask smart questions. Follow the words of William James and recognize that "Truth is what works." Find what works for you and keep refining and fine-tuning it to make it better.
