I'm not a SWE, but I will say often when these types of posts come up, people throw in "work on your management/people skills!" - even if you never manage, interpersonal skills in the work place can be just as useful as any hard skills. Here are three books I recommend:

Good luck on your journey, the fact that you're even asking these things is a great sign. :)
