This is the appropriate attitude I think. I also have a sense of not being 'worthy' much of the time with this, which is not something I usually have with other psychedelics but should probably have more of. There's a reason DMT never took off in the psychedelic 60's compared with shrooms and acid. Partly its the ROA and the power of it but those other psychs lend themselves much more to hedonism and reverie. There is of course nothing wrong with this in itself if not done to excess, but in a way DMT precludes that by its nature.
Also because it's direct access to that pure Presence there is no hiding from it and its natural to want to eliminate negative traits the more you commune.
I'm glad you report this also, I knew it had to be a far more common experience. Along with
@Voidmatrix reports I think we can safely call the 'DMT Calling' a verifiable phenomena to look out for now in the DMT user landscape rather than simply an anomaly, I have spoken to others who have heard it also. The occurrance of the sound in sync with activities you do in your normal life is important as its part of the communication of the DMT Dimension and your relationship with it as it guides your path. If you notice any significant occurrances of the sound then share it as it is intriguing as to how the DMT communicates with us outside of tripping and the relationship to our use.
Self destructive behaviours and overcoming them are part and parcel of the process of developing oneself. Some of them may be due to negative learned behaviours or from prior associations, or may have been coping responses to difficulties that became a crutch.
I also think however that a lot of it stems from a fear of our own power and potential. We dare not acknowledge our true capabilities so its often easier to revert to a lesser version of ourselves especially if that version is being reinforced by others also living in such a way.
The DMT Dimension shows us a better version of ourselves and the challenge is to meet and stabliize it in daily life, after which an even more well integrated and improved version will be shown next time and it continues if you can meet it. I would say breakthrough is less important than gradually opening to the insights shown and like any challenging path, accepting the certain amount of anxiety that is involved is part of that growth.
