Having a little extra time in my hand now, and not wanting to waste it away by watching online videos, I thought of some really cool things (I am sure most normal people would not find this list as cool :) ) I could do:

• Create a flat file PHP-based database management system
  
• Work on the "MLS" project idea ("MLS" is a self-given acronym to one of my ideas)
• Contribute to some Open Source Project(s)
• Learn about how PAR files work. I read a little about them, I found it very cool and interesting
