You've got a lot of advice, but since I've been in your shoes, and little of this would have been much help to me, here's one more opinion:
As you go about your current life, whatever that includes, there will be moments where you feel a stirring of interest or excitement, like when you're walking around a city and you catch a whiff of baking bread somewhere; or hear music playing somewhere. And then you keep walking and it's gone.
You can start orienting to that smell of baking bread. Trying to walk toward it so that it gets stronger instead of disappearing.
That's it. That's the recipe.
What counts as the smell of baking bread will be different for you vs others. I don't know what it is and you might not, either. That's the beauty of the technique, your model of yourself is probably garbage, unless you've been living a very particular life you won't have a good idea of what you need. But being alert to what's alive in you from moment to moment is a reliable guide.
Nothing more is required than to attend, and then to act on what you notice. You'll discover something important. It's been very helpful to me.
