This happened right after a very difficult point of my life, when I lost most of my motivation due to heavy self doubt and depression. My blank year was spent dealing with searching for other things I could do, trying to manage my life for better, but in the end, it amounted to not too much. In my final desperation, I went back to my home country, back to a little tiny apartment with nothing but a small package.
There, I started to live all by myself for a few weeks and for some reason I began to have fun. I'm not so sure what managed to bring back my mood, since I haven't changed my lifestyle too srastically at that point, so as of right now I just point it out to be a change in environment.
This tip had me experiencing a life, where I had not many support both financially and mentally, just sorting out my thoughts in my mind quietly.
