When i read the book from Tad james about time lines he tells to clear out first the black spots on peoples timelines en then do the next move.
But my NLP Trainer said:"leave them alone cause people put theire traumetic experiences, ext.. in their. Its too dangerous."

Can anyone give some advise please? thx.

Remember that you don't really have a timeline. It's a useful metaphor to play with sometimes - an imaginative way to represent your mental map of the world - but keep in mind that you're only constructing and reconstructing your own thoughts. And thoughts aren't real.

You asked for advice, but all I can tell you is my own experience. I find life more pleasant when I embrace what's happening right now. There are no black spots in the real world. So just put your feet on the ground, take a deep breath and realise that what's real for you right now is what you're experiencing through your senses. The more you live in the moment, the more wonderful your life will be.
