Diamond Hands, the way to earn big in Real Estate?

[Ammar Ali]

For those unfamiliar with the term, "Diamond Hands" is a term generated by the retail stock investor community indicating that if an investor holds a stock for an extended period of time, or has "diamond hands", they will always eventually see a profit.

Mentors and veteran brokers and agents have told me even their most botched transactions of the past always end up profitable in the long term. Does this ring true in everyone else's experience?
