First, I’m definitely not the right person to be suggesting anything, leave alone advice. However, I really hope my words will give you another perspective.
Your description hits me as if you are describing me, extremely close to me.
I had some successes very early in my career that propelled my ego and made me, in my wife’s word, “a heartless bloody bastard.”
After I had been failing one after the other in my attempts, punctuated with two (or is it three) tiny successes/exits. My wife is worried that with this much of failures and rejections, I’m not gone crazy and can still stay cool and nonchalant.
About Climate Change - that is the other thing - I think I have found my ultimate happy place, do something to help fight Climate Change. It may be a losing battle but I need to fight for my daughters.
Spend time with yours family, friends. Many usually advices to keep business and personal separate. I’d say, can you weave them so you are your ups and downs flow together and you can live with them.
Also meditation (perhaps guided) helps. My best friend (a neighbor whom I grew up with) died (of a curable sickness) after I ran off from my hometown for a better life. I will never forgive myself for not being there when he needed me. Whenever I take part of guided medication, the only thing I remember is our adventures along the shallow rivers which we did regularly while growing up (teen-years). I’m not happy, perhaps I’m sad but I feel at peace that I can vividly remember him, our conversations, acting out our Star Trek fantasies.
Please fight it out. Pick a cause - climate, friends, relations, family. Your aims and ambitions will be arbitrary for others but it is the ultimate scale to measure yourself against.
I’m not religious at all. However, my sister and her family is. When they are in my town, I’m the chauffeur that takes them to various templates and places of worship. I either read or stay silent and listen to some of the priest narrating sections of Mahabharata. The relatives are happy and I like that people around me are happy.
Finally, help others (founders, entrepreneurs, and many others) without expecting anything in return. Perhaps, the fun and adventurous part is to help others without letting them know you help them.
Life becomes lot more meaningful. These are the few notes from a tiny piece of my perspective. Please pick your own as I may come in “heartless” coming from a broken family, struggled/fought to eat/live since an early age, seen abysmal lows that anything that happens onwards are pretty high.
