Hopefully within the next five years I will be at a place on the career spectrum where I'll be able to laugh at myself for this... because getting nervous about changing just one cue of someone else's is ridiculous.
note: I also got nervous on day 1, rightfully slow. Learning curve was a little steeper than it should've been.
PS. I should take this opportunity to tell you that while tech makes you tired, when it's with great people, it makes my heart optimistic about the "rightness" of my choices. Thank you, world.
