I resigned and studied at home for couple months, I self-studied from MIT OCW to MOOC. Recently I found this article is a good summary for MOOC resource (in Mandarin) that you could evaluate, depend on your willing and passion.

MOOC不止可汗學院、Coursera和edX：更多大規模開放在線課程介紹

In this article, you could pick the MOOC resource in knowledge or in practice, I basically took MIT OCW, Cousera, Udacity, edX, Khan Academy …etc. I love their passion and learn much that I seldom cared about while I was busy. Take the LFS101x, Introduction to Linux of edX, as example, I enjoyed it to review my Linux domain knowledge. There are 18 chapters, depth from beginner to expert, I took time watching it and gain knowledge.

In a nuts shell, take a short time to review your career, interest, passion, then make some decision when you’re available. It’s up to you, your passion to find something to die for, no matter how to choose for life or work.

-Cheers.
