Happiness is an abstract feeling. Do what you like ! Love who you like ! Spend precious time with one you care ! ...See thing with faith and choose what you want that to be...positive/negative, white/black , sad/happy , up/down, good/bad....else make your own happiness the way you like.
I found one now and thought to share for good. For very first time, I kind of seriously worked on some Ad video production from head to toe for a video contest. Spent time to think for idea, think on aspect of video production/edit/audio/camera shooting/visual effect/software/hardware...etc. It was tough for a novice to adapt to real work need in order to complete a video clip. I enjoyed the process very much and cherish every moment and experience I have gone through and printed a satisfactory smile on my face. The video is not distributable for the sake of contest, else I would rather share it.
In fact, I admired most who made a great commercial and I pretty 'ambitious' to make my name one day to have similar prospect in Ad production world for the place I can find more satisfaction and happiness. I love art from music, song , design (commersial), to video filming more than anything I do in my current profession (of course, there also something good in there ;p).
