How to design a portfolio with 10% p.a. return?

[shorthair]

Hi

Is it posible to achieve 10% return p.a. via an investment portfolio?

If yes, how many percentage should be in the stock market, real estate, mutual fund, or any alternative investments?

Is borrowing for investment worth it? How do you leverage other people money to obtain profit? What are the risk that we need to look at?

Thank you in advance.
