Somehow I feel like I do this already when I encounter so many people who I used to be like I was in the past, but even if I gave them any advice, they often still find some reason to deny themselves, perpetuating the wallowing in their own despair. I wouldn't necessarily give my younger self advice if I did any form of time-travel to advise myself, but rather, I know what I would personally do differently if I ever had to re-start any kind of earth-life from birth-phase.
For one, I would choose a better set of parents, ones who were more nurturing, non-abusive, wise, and not brain-washed by any kind of cult-beliefs or religious-beliefs (such as belief in government or anything status-quo). Ultimately, I think the most-important thing that anybody can learn in their whole entire eternal-existence is to simply have the ability to be able to question everything, and if my younger-self can learn to double-check everything that he thinks he knows about reality, triple-check, heck, even quadruple-check & compare & subject it to the most diametrically opposed criticism that he may find against his paradigm, and be able to make his own decisions, without always insisting on needing to rely on any so-called experts (because it turns out that a lot of experts really are just so-called), then I would regard that as progress (actually, better yet, I would write a detailed letter as to how I fully lived out my life, what I learned, and pass on all of the knowledge/wisdom along with various recommendations as to what/how I would do things differently, thus giving all of the secrets behind the potential things that could happen in his future, and how to negate the negatives whilst taking advantage of the positives).
