Went to bed at around 3.30am last night this morning.
Realised I was actually rolling on my bed for almost an hour.
I was unable to fall asleep despite going to bed THAT late.
Then I realised I was thinking about my portfolio all the while.
My worries for my portfolio must be the cause of all this rolling on bed.
I should stop thinking about it and think of something else, I told myself.
So I pushed the thoughts about my portfolio aside and thought about fandom stuff.
I fell asleep almost immediately.

Conclusion:
Portfolio kills braincells.
