Obsessive thoughts about impressing other people

For the previous 6 month, I had silly irrational thoughts that I progressively build the habit of thinking about them. Those thoughts involves me impressing some people somehow , somewhere. I experience many variations of them but the same theme. It all starts when I imagined myself solving a rubik's cube then that thought was repeated then changed a bit and so on. Now, I can't even control it. it feels like i can't control it. For the worst, My mind is projecting these ideas on almost anything I feel I am good at with random people i met on random places i visited.
This state has serious effects on me. not to mention wasting time doing insane actions like talking loud to imaginative people but I also suffer badly after it's over . I can't concentrate, talk, even think normally. it feels like all my cognitive resources were consumed. In addition, I made terrible blunders in actual social situations with actual people which make me avoid people which, i think, fire those thoughts.
I've tried things including mindfulness, yoga, writing , changing diet, exercising, talking to close people more ... all that seems to work temporarily. I need a better understanding to know how to tackle this big fat problem or at least any action plan to try.

This is an interesting thread , I can relate it to issues of the obsessive need to be accepted or liked for what ever reason maybe..? Maybe it's just my Pure O thinking it's related but it makes some kinda sense.. hmm :O
