The person most comfortable in their own skin always wins. Guy's wife, kid, etc comes across some luxury travel video, finds out an acquaintance or another parent recently bought a huge house, says something innocent like "omg that's a dream" to him
Guy who loves himself naturally responds with lightness. Says that's amazing, I'm so stoked for them, there's so many beautiful things in the world and he genuinely means it. Guy who doesn't will always give off some sort of energetic tell that maybe reveals he's jealous, punctures his confidence, makes a remark like "probably family money" or something etc
Indirectly teaches everyone around him how to perceive him. "Through my repeatedly low vibrational reactions I'm signaling to you that my self worth is derived from comparison, so inevitably via osmosis you will start to view life through that same lens as well"
Manifestation. Create your own reality. "I'm under so much pressure to meet expectations so they won't think I'm not good enough etc" wrong he turned that belief into the truth on his own and roped others into his field of influence. How he perceives himself is how others will perceive him. Perceive more abundantly, more genuinely, and people have no choice but to follow that lead
Most relationship problems are ultimately just a lust for life problem. Gf/wife unhappy, kids distant, some disconnect with the family etc. You try to solve the discomfort through tangible achievement. Think it's because you're not making enough, providing enough, "successful" enough
You need to upsize the house, upgrade the vacations, perform more, show off more. Not realizing that this comparison based expectation you created in your mind and how it subsequently causes you to behave is exactly what's causing the problems in the first place
Meanwhile the only problem is just a severe lack of vitality. You're boring and moody and see reality as an obligation and take yourself way too seriously. You're not a beacon of energy, you don't inspire the people around you, you don't inject wonder and curiosity into their lives. There's no adventure, no spontaneity, no presence. You lost their love because you lost the love for yourself
