I saw this somewhere and I think I should ask here too.
If you plan to fail and you succeed, which of the two did you do?
When someone plans to fail, they typically set themselves up for failure by making decisions or taking actions that they believe will lead to an unsuccessful outcome. However, if despite their efforts to fail, they end up achieving success, it means that their plan did not go as intended.
If you plan to fail and you succeed, then you have actually failed to fail, which means you have succeeded unintentionally.
