What is the most useful skill I can develop in 3 months?
I am 17 and finished high school last year.I spent the last 7 months travelling and now I have three months of free time. I'd like to learn something that could eventually lead to some income and/or be useful for the rest of my life, in any way.Thanks in advance for your answer !

There is a great Ted Talk you might be interested in:
Three months is more than enough time to not only experiment with different skills, but to actually learn them to a fair degree. You could conceivably learn around 12 new skills during that time at a lazy pace, or around 24 with the same time commitment as a full-time job (40 hours per week).
That said, I would highly recommend the skill of "learning how to learn". Consider it the compound interest of education. Focusing on it this early in life will allow you to learn new things more easily and more fully for the rest of your life!
She also has a book (How to Excel at Math and Science (Even If You Flunked Algebra): Barbara Oakley: 9780399165245: Amazon.com: Books) (don't be thrown off by the title; it's literally her Ted Talk in book form), and a free Coursera class (https://www.coursera.org/learn/l...).
Along the same lines, did you know that you can train your own memory like any other skill? Imagine how fast you could learn new subjects if you could memorize foreign language vocabulary, the periodic table, or geographical facts instantly with little effort! For that, you'll want to read Amazon.com: Remember Everything You Want and Manage the Rest: Improve Your Memory and Learning, Organize Your Brain, and Effectively Manage Your Knowledge eBook: Helmut Sachs: Kindle Store
and
The Memory Book: The Classic Guide to Improving Your Memory at Work, at School, and at Play.
Finally, mental math is a skill that will come in handy for the rest of your life. For this, you'll want to read Secrets of Mental Math: The Mathemagician's Guide to Lightning Calculation and Amazing Math Tricks, Arthur Benjamin, Michael Shermer (and can generate practice problems at Math Worksheet Generator).
With those three skills under your belt, there's really no limit to how far you'll be able to go in your chosen field. Good luck!
[Edit] As far as actual business-applicable skills go, there are three that have proven to be invaluable in my own life: Photoshop, Excel, and programming. If you can learn those three, you can do anything.
