Here are my top three pieces of advice I wish I had at 15:
Remember: every website you use, every app on your phone, was built by people just like you. There is nothing magical or mystical about technology. Technology is just a tool, and you can learn to master it to solve problems.
If you can see problems in the world, be it not remembering to walk the dog, or being annoyed with washing your car, you probably have an idea for a business. It might not be a billion dollar business, but it will get you thinking.
Get in the habit of starting things. We spend so much of our life planning, waiting, when we should be trying, iterating.
Further to your advice of getting into the habit of starting things, I think it's invaluable to also having the habit of finishing what you started.
I'm not saying be incredibly pedantic about it, but finish the things you want to work on. Started that app that you love? Make sure you specify time to work on it. Too often when I was 15 I started projects but never got to a significant stage with them due to wanting to do too much at once or playing silly games like World of Warcraft.
