Cards on the table -- I'm a massive fan of mentoring! So it's a big yes for mentoring from me.
We all need help now and again. Help in the form of unbiased support, a friendly prod to move things along, maybe just an understanding ear. I've found that those who say they don't need help often need it the most!
Whatever your role, whatever your level, I'd strongly recommend you consider working with a mentor. I have a fabulous mentor myself and as a result feel like my business is getting the support it needs, when it needs it, to realise the goals we've set.
