Graduation is often seen as the end, the completion, and to some extent it is, but you should never stop learning. In my field, which is half creative and half technical, programs are always changing with new technology. One instructor said he has worked with 12-15 different programs in about 20 years.
Things are going to change and as professionals, we will have to adapt. We have the internet at our disposal. So there is really no excuse to let technology pass you by. I spent about 2 hours the other night watching tutorials on a photo technique because it looks like fun to try. I plan to experiment in the near future with it.
In the end, the concepts and procedures matter but the programs we use don’t. If you can make a great movie in Sony Vegas, do it but don’t be afraid of other systems and platforms.
And do things for fun. Teach yourself a skill because you want to and it makes you happy. Life is too short to be unhappy.
