There are two kinds of income. When you work on your job, “How many times you get paid for every hour you work?” if your answer is “Just once.” It means you are working for linear income. But when someone write a book, he spends let’s say 500 hours to write that book, he will get paid again and again for that work whenever someone will buy that book. It is residual income.
The real secret of wealth is that whoever will be able to create residual streams of income will become wealthy. You need to create residual income streams where you have no need to hire employee and your presence is not required. Money will keep flowing in every month and you will have a lot of time to do whatever you want.
