Always prep. Take time with a list of questions for both you and the "expert."Each question should lead you to the direction you need. Understand it may take 3-5 min to fully answer the question, longer for more technical ones. Let them answer the questions while you take notes. Be sure not to interrupt the answering portion; save your questions for the end to avoid rabbit trails.

Will power and determination go hand and hand. Many people struggle with the "want" aspect of their work. If you would start by getting minor accomplishments, after your breaks, in order to gain momentum, it will help. Many people will say you should find something that is more to your liking but thats not always feasible, however if it is I would consider it. If not, be determined and will power will begin to manifest.
