Key

I have been thinking a lot recently.
Thinking about all sort of things, my courses, musics, revisions, family...
Why am I working so hard in my study and job?
I can't find an answer, not even a reason.

I am looking for a key.
A key to open a lock to free myself from stress and negative thinkings.
Or may be to open a door so I can escape from this breatheless workloads.
