Both in professional and personal relationships.
As I get older (turning 22 this year) I feel that it's harder to find out what I'm doing wrong or could do better. People are less frank because you're a grown human being and there's nothing for them to gain from it. I consider myself really open to criticism and want to hear what people think, but not everybody is like this, so there's also a fear of being reprimanded.
When you're six and forget your manners, your parents can quickly correct you. When you're a junior software engineer and break production, the senior can point out your mistake and help you to learn from it. But beyond this, there's only really close friends, family, and significant others that can help.
For most individuals, there will be an inflection point where their parents know them less and less as they get older and eventually a romantic partner becomes the person most familiar with them. Then there's a whole new person to learn from.
If you're not dating, what happens? Nobody really knows you, unless you're lucky to have close friends who you see often. So, there's nobody to observe you and help you grow.
Hope this explains my question sufficiently.
See if you can identify patterns in your thinking and behaviour. Make sure you know what your focus and targets are and ask yourself if what you are doing is bringing you closer or further away from those goals. If it is the latter, continue asking yourself questions to find out what you need to do to course correct.
Also, read widely. Something like Tim Ferris’s Tribe of Mentors will expose you to a wide variety of different high performing individuals and their thought processes and habits. Reading through you can see if anything resonates with you and you can decide if you want to incorporate it into your own life. If you do find someone who you resonate with, find out who their influences are and what books and podcasts they recommend.
Finally, try hard, challenging things at the edge of your ability. If you fail, you’ll have found something out about yourself and what you might need to work on. If you succeed, you’ll still have learned some valuable information and you also get the satisfaction of completing a difficult task.
