Ask HN: Deal with feeling of not knowing anything well enough?
3 by utopianmonk | 1 comments on Hacker News.
I've spent 15 years in the tech industry, working with well-known tech companies and engaging in projects that I'm proud of. My main focus has been on creating reliable, widely-used distributed systems. However, I often feel like I lack in-depth knowledge. The challenges I face seem quite similar, like working with building blocks. My approach involves learning what's necessary to solve immediate issues and then moving on. I'm unsure how to reach the expertise level of industry leaders like Brenden Gregg and Jeff Dean. It might be like having Impostor Syndrome. But I do believe I have some knowledge and can use it effectively, but there’s also a sense that I lack deep understanding. How can I handle this situation? What steps can I take to achieve even just a small portion of their expertise?
