I highly recommend this book, it’s not only directed to adults but teenagers as well. It teaches you how to form consistent habits and a durable system for productivity. Even if you want to start a new hobby or learn a new skill this summer, this book will definitely help.
Atomic Habits by James Clear
If you’re having trouble changing your habits, the problem isn’t you. The problem is your system. Bad habits repeat themselves again and again not because you don’t want to change, but because you have the wrong system for change. You do not rise to the level of your goals. You fall to the level of your systems. Here, you’ll get a proven system that can take you to new heights.
Learn how to:
* make time for new habits (even when life gets crazy);
* overcome a lack of motivation and willpower;
* design your environment to make success easier;
* get back on track when you fall off course;
…and much more.
