Part 1 here.
Part 2 here.
I’ll just do part 3 now because I can.
A big ego helps
My ego has inflated massively in the five or so months I’ve been at my company. In some ways it’s caused me a bit of trouble (it’s certainly not a good habit for me to talk over my boss sometimes!), but it’s been mostly beneficial. If I didn’t believe I was all that and a bag of chips, I would have had less confidence in my skills, I would have felt less comfortable helping lead efforts to educate the new waves of SDETs we’ve hired the past couple of months.
Even long before that, when I began participating and giving presentations for my university’s web developer club, I had to have some level of confidence in my skills for me to feel comfortable demonstrating them to the others. I had to believe that I had something they didn’t have. When I became a secretary for the club, I had to believe I was the best man for the job to run for the position.
Your ego doesn’t have to be massive like mine has become, and especially if you’re first starting out you don’t want to come across as a know it all. But you do need to be able to believe that your leadership is valuable, and therefore believe that you are more capable than other individuals around you.
