Here are the top results:

Learn a musical instrument (guitar, piano, etc.) - 31%

Learn a new language (Spanish, French, etc.) - 25%

Learn a new sport (surfing, snowboarding, etc.) - 11%

Learn to cook (Thai, Japanese, etc.) - 10%

But it didn't stop there. We asked them why they haven't done it yet - and 65% of them said they just "never got around to it".

So we took our favorite answers and turned them into free introduction guides. Sometimes the hardest thing about learning something new is just getting to the starting line.
