I´m agree with John Gu, stay active. The most of the time this feeling is caused for be pasive, pasive in this sense, be used by others, like a tool for their own interests, do and live like others want that you live your life. The most of the time in
this current economical system we are pasive, and in the most important ambient, in the job (where we should feel creative and active). In this system we are in the job, how many hours each day? per week? and usually in the job, we are an element more, a part
in the machine. Not decision, and sometimes also don´t think. Humans and things are differents.
Be active is be and do the things that you really feel that you want to do, the things that you decide. Create things (painting, writting....) or create a crazy party night with your real friends or in a simple chat with a friend, without topics, being yourself
without social masks, are first steps.
in any case, my english sucks, if you have interest you can look for some books of the psychology, Eric Fromm, he wrote about this, the human in the current society.
