Ideas for quests to level up?

I like doing missions/quests like this:

• Touch Everyone
  
• Smile and Eye Contact Experiment
  
• Ask cashiers how their day is going
  
• Ask twenty people on the street what time it is.
  
• Ask twenty people on the street how their day is going.
  
• etc
  

There are several reasons I like things like this:

• Emphasis on action over theory. - I read too much. I need to get out more.

• Start small and build up. - This is the proper way to train any skill. Jumping in the deep end can be traumatizing.

• Train one skill at a time. - Approaching a girl and trying to remember eye contact, posture, questions vs. statements, conversation threading, kino, body language, and smiling all at the same time is difficult. Concentrate on one thing until it becomes natural, then move to the next thing.

What are some other ideas for things to do to progressively level up?
