Multiple source of incomes

I am intent to increase my other source of incomes (other than normal salary income) to 20% of my total annual income by the end of this year.

Here I listed down some possible source of incomes I can generate over the remaining 10 months period:

1.) Investment Gain / Dividends / Interests
2.) Rental income
3.) Freelance job (work at home) income
4.) Government cash bonus
5.) Others

My ultimate goal is to increase my non-salary income to 50% before reaching 40s.
