Great video man. I couldn´t agree more, it is so different from person to person. But I always like to start out small and see things grow. I also know of people who have started out with NOTHING at all.
I just invested $160 in slacks & dress shirts last month... I didn't get the job I wanted which required that attire, BUT I did use those clothes for other interviews which ultimately landed my current job... also in the flip side nice clothes in general helped boost my confidence. nice video.
