It'd be a needed skill

• not to keep one's heart in a sleeve, in a very short sleeve.
• to be able to be completely honest to yourself, and to others, in every situation ie. not to hide any feeling.
• to see in future to avoid possible misjudgements.
• not to see connections between everything. (City of Angels has closer connection (in sense of similarity) to my own life than I thought. Which I realised yesterday. Which was extremely bittersweet.)
• to be less afraid.

It'd be also great skill to avoid getting sick. Which seems to be now.
