Serious personal tragedy can compress the middle phase into a very short period of time. Comedy is born where hope dies. Devastating disease or injury, a long jail sentence, a ruinous lawsuit, living through a war, etc. Most of the quick routes to lifelong wisdom are not desirable.
For me it came not long ago (just starting my 40s): A film I was just watching had a great quote: "The universe isn't evil but it sure has a nasty sense of humour: I found the person I should am meant to be with, but I can't be with her"
Something vaguely similar happened to me: I suffered from a very strong cronic IBS-C for 20 years, since my University time. Around January 2022, I found a real cure for this 20 year long ailment (a very specific probiotic strain). I spent a couple of weeks really living amazingly, as I haven't lived in 20 years.
Then, on February I got the Astra Zeneca booster COVID vaccine, and as a result, I got long COVID symptoms and a stroke (Transient ischemic attack), and now I'm on aspirin for the rest of my life, and feeling like shit.
Aaah the universe has a nasty sense of humor indeed.
Unfortunately, I don't think you can. I think each phase builds on the prior one; the life experience informing the emotions you feel.
The tragic phase is a result of not living up to the unrealistic expectations one has, and the comedic phase is a result of dealing with those tragic emotions.
And there's always Tony Robbins, Jordan Peterson, and a wealth of other self-help types. Picking any system is better than nothing, and gives you context for selecting good ones once you're familiar. Coast on other people's wisdom until you earn your own.
I despair at the modern trope of dismissing something of worth due to a person's thoughts/actions in an unrelated area (in modern parlance, "cancelling" someone). It seems like an ad hominem attack to me. How will this trend evolve in the future? Will the works of people like Beethoven, da Vinci, Einstein be cancelled due to them being meat eaters? (Substitute someone of equal stature if the people listed are actually vegetarians)
Life wisdom would seem to be an area where you should be wary of following advice from serial sex abusers... (I know nothing of Robbins, I just wanted to discuss the general heuristic).
I would encourage you to read at least the Wikipedia page of Robbins. I’m no fan of cancel culture either, but he doesn’t seem like a good person or someone I’d take advice from.
You can experience heroic drama, tragedy, and comedy all at the same time or all within the same day. Just look for them as they happen. Or think back to what you did yesterday and interpret what you did from the perspective of each of these stages.
Maybe you are closer to it than you realise. I don't think there are age limits to any of this stuff. A decade of life for one man, is but a Tuesday of another.
