Investment does not mean income.It would be a big mistake to think that investing here means income.Many investors have lost their capital by investing without realizing it.So you should invest knowingly before investing.And you should not invest in any project.You should invest wisely.
I agree with you! People usually think of investment in term of money. However, the first investment that every investors should make in this market is investing their time. They have to use their time to learn, to know, to practice, to experience the market before they can make any investment. Otherwise, they will invest in something they don't know well which is very risky!
