Wisdom … does not come from experience. The only thing the trial and error method gives you is experience overcoming errors, think Thomas Edison.
Wisdom … comes from being intuitive and insightful, both originate from your High Self (Aumakua in Huna), think Nikola Tesla.
Intuition is guidance/information you receive when in an unconscious state, meaning you are not consciously communing with your High Self, such as when day dreaming or dreaming while sleeping. Insight is guidance/information you receive when in conscious communication with your High Self, when in a conscious meditative state.
Your High Self knows why you are here and one of their responsibilities is too provide you with the opportunities in your life to achieve your goals. Another of their responsibilities is to protect you from what could be referred to as dis-incarnate spirits and other entities that would and often do pose as wise beings offering all kinds of good sounding guidance and information. The weaker your connection to High Self the easier it is to be misled/unwise.
If you don’t have a strong connection to your High Self, it is vitally important that you pay attention to your gut feeling when evaluating any guidance or information presented to you regardless of the source, including what I have written here; a bad feeling in your gut is your High Self’s way of letting you know to stop and walk away because what you have received is not part of your truth and will not get you where you said you wanted to go during this lifetime. Ignoring your gut is very unwise.
