I'll give you an alternate comment which will not be pleasant. The bolded statement is untrue statement. Life experience last forever till the eternity, no one can ever take it away from you, neither it can crumbles into ashes. Only the material resources can be taken away. Similarly in life, when you are at the end phase of your biological life, you cannot take the wealth you accumulated in this realm with you but only the life experiences.

Since the ancient time, it has been made known, that to be able to keep or guard the treasure or beauty, you must have the capabilities or abilities be it in form of strength, wisdom or intelligence. If you do not have the capabilities, it is the matter of time the treasure or beauty will be taken away by brute forces or tricks. This statement resonated well with the modern days idiom " a fool and his money will soon be departed".

Example of the such event - blood diamond. Those who fallen into calamity by the possession of the blood diamond, do not have the ability to protect it & themselves. If the blood diamond was possessed by individual like Putin, chances of the calamity to happen decreases greatly because ppl like Putin has the ability to protect the treasure.

Likewise in the present days, why so many cases of scammers happening to the individual with the inheritance from their late parent / spouse. It is because they do not have the ability or capability to guard the wealth.

Your partner case, you have to convey the hard fact to him. He failed because there is something missing in his journey. He need to unlearn all the things he know in the past and start learning again. Being remorseful about the past will not change any state until you put effort to make thing works again. The sooner he let go the past & start working on himself again, the sooner he can see improvement. The longer he drags, the more time he will waste in this life.

In the modern day, there is another popular Law's - Wilson's Law : "If you prioritize knowledge and intelligence, money will follow".

A mentally strong man will stand up on his own. If your man is mentally weak, you need to take lead in this.
