This isn’t meant to give you permission to be arrogant or to completely overlook other’s opinions of you. Heaven knows constructive feedback is very useful. However, managing your own opinion of yourself is most important because it’s the gateway to helping you decide how and what to pay attention to, what you can and cannot do, and what you should and should not do.
If you have a lofty opinion of yourself, you may exclude useful criticism and advice. If your opinion of yourself is lower than it should be, you may also exclude useful information, or you may end up kowtowing just to gain approval.
Be honest in your own self appraisal. Remember, it’s ultimately your own opinion that wins in the end, even if you pretend it’s someone else’s opinion that you’re harboring.
Other's thoughts and opinions are their own business.
Do no harm, take no sh*t.
