New hobbies

So I've been entertaining myself by trying to pick up new "hobbies". Here are the things I've tried so farm and approximately how long they've lasted:

• Learning Python (1 day)
• Reading books (1 book, unfinished)
• Online dating (1.5 months)
• Makeup (2 months)
• Calligraphy (2 months)
• Learning HTML and CSS (1 week)
• Crochet (1 hat, unfinished)
• Sewing (bought fabric, never started)

And the things that I've thought about trying but have yet to make any real effort to pursue:

• Yoga (or some form of exercising)
• Cooking
