Let's do your doctor first: You have killing pain that just started off say in the legs to all across your body, and you rush to your doctor. Your doctor asks you: "Let's run through you previous few days' activities. Including food consumption, environments you have been in, activities you have done that could've caused strain, and medical history."

What would your response be like?

If you're any sane person, you will not simply 'forget' to mention to your doctor that you spent 12 hours listening to loud music while eating food that can only be classified as junk. You will not forget to mention the fact that you had jaundice a couple of months before, which had already weakened your immune system, big time. Now let me ask you this: WHY? Why are you so honest with your doctor? Oh I know why! Because you know in your heart that if you don't tell him just how much you have messed up your system, the doctor might put you on low dosage medication, which will nowhere be enough to bring you back to normal from where you currently are. You KNOW that you need to lay it all on the table, and you know you're doing it for YOU.

Similarly with your lawyer, if you've ever needed one. You know for sure that you need to tell your lawyer EVERY goddamn thing, including random stuff you said or did in random conversations which might come back to bite your ass when you least expect it. You're again doing this, because at the end of the day, you're putting yourself first. You want to be saved.

Now let's talk about your mentor. Remember the excuses you gave for not having done the work you were supposed to? What about the times when you didn't tell how badly you screwed something up, simply because you thought you could manage, and then your mentor gave you a graph he expected you to meet- and OBVIOUSLY you couldn't, because you were climbing out of a hellhole at that time! You weren't on solid ground ready to take flight. But hey, did you tell your mentor this? NO. Why not? Well, because.. You could handle it yourself? See THAT'S the difference between your doctor/lawyer and your mentor. Your doctor is someone you visit when you're absolutely NOT OK, when routine life becomes difficult. But your mentor? He's somebody you go to, to make your routine life translate to awesomeness.
And when you can be so honest with a doctor whose sole interest is to bring your life back to normalcy, why can't you do the same with a mentor, who will help you soar high above normalcy where traffic is a non-existent word?

Rewiring your brain is a very possible thing, but first, both your doctor, and your mentor, need to know how it is currently wired! Be honest, be awesome!
