Studies (and rumours) have shown that mentoring and networking is tied to competency & success. However, no one ever talks about the fact that mentoring isn't easy.

Mentoring poses a few problems:

1 - it’s hard to mentor. It’s hard to put a process (thought, procedure or administrative) to how you got somewhere or achieved something. It’s much harder if you’ve ever tried to repeat a specific success. And even harder when you understand how much personal style plays a factor.

2 - it’s hard to be mentored. It’s easy to get advice but much harder to take it. 

3 - most importantly - mentoring isn’t a guarantee of success. It’s not a magic pill or a silver bullet

However, it is also true that you will be more successful if you add mentoring. No one ever says "mentoring held me back!"
