Self-understanding and reflection constitute the fourth element that I would like to discuss.
The more experienced people can look back in their own longer histories (on work and life) and reflect on what has worked and what can be improved on.
Assuming the same state of mind, we do have more experience and lessons to be drawn on when we are faced with challenges and problems.
Having said that, it should not stop us from being creative in seeking new solutions.
Use it wisely.
