Surround yourself with good friends and family. People who are positive and cheerful. Those who will motivate you and provide you with constructive criticism when necessary.
It is very important to be around such good people and try to avoid people who will try to demotivate you without any valid rationale behind it.
I read books and provide quick dense insightful points of the book. I also omit some points of a book if they are repetitive and are found in various other books. You can also find some deep thoughtful quotes here. Cheers.
