This is a quick hack, may or may not work for you. I tend to be pretty negative, passive, and not impressed easily. Usually I am in bad mood or pissed of some random news. I used to come off in interviews as uninterested or shy person. Then I discovered effects of sugar and caffeine. Now during interviews or other social/professional engagements, I drink a big sugary caffeinated drink beforehand. It changes my mood to positive, I am more hyper and talkative. It might me just my crutch or just in my head but it seems to help me temporarily. For long term fix, I have tried many things like meditation, yoga, cardio, weights, but nothing seems to work. Also get your blood work done. My doctor once told me that I had low testosterone level. He suggested it could be reason behind bad mood. He wanted me to workout more to improve it. I have been working out a lot more since then and have achieved a decent muscle definition but I am still negative and passive.
