Honesty is everything. Trust is everything. If you do not understand yourself, do not hide it from others. If you do not understand yourself, do not hide it from yourself. 

You work with other people. To know them, you must first know yourself. You must first understand yourself. 

Be honest about everything. If you do not know what you can do, do not hide it. Let people know. To do well, you must know what your strengths are and what your weaknesses are. 

And the best way to figure it out is to pay attention to what makes you really happy. Always think like a student, not as an expert. Experts know everything. But students are learners. 

If you want to grow, it is better to think like a student than to think like an expert. 

Whatever you do not know, admit that you do not know it. If you have done it before, let them know what you can do. If you haven't done it before, let them know what you do not know. 
Do not be scared to admit that you do not know something. 
Look, if you want to learn, if you want to grow, if you want to add value to your life, it is better to look foolish for five minutes than to look foolish forever. 
If you want to grow, keep learning.
