And this is where this kind of tutorial comes in handy. As long as you want to be mentored, you're on the right track. Don't be afraid seeming dense and asking dull questions becasue that's the idea. Whenever you meet your mentor, be it once or twice a week, ask him whatever you have been thinking about. He agreed to this and wants to guide you on your path to success.
Questions are useless only when left unanswered.
Have a list of questions that you want answered. The ultimate goal is to arrive at a stage where you will no longer require the services of the tutor and will be able to make it on your own. When you outgrow your mentor, move on. Perhaps giving something back and becoming a mentor yourself will continue to increase your learning curve at this point. You've been working at the same company for years, it's time to request a raise.
