Consistency is the key to increasing income. If you make constant profit and follow many management rules your income will be increasing over time. For example, you have 100$ in your account. First month you make 10% profit so 10$. Now you have 110$ in your account. Next you also make a 10% return that means 11$. So you have 1$ increased in your income.
