...over the past few months:
1. Being able to make a choice (food, how to spend my time, what to wear) is not the same as being forced to take the worst/easiest option.
2. Owning a book is not the same as having mastery over its contents.
3. Having the tools for X is not the same as having the time (or attention) to become good at X.
Being an adult means learning these sorts of things.
