Buy and forget

After changing strategy in stock investment this year, I think buying counter with high dividend is the best. After comparing Stareit and public mutual, I actually manage to gain at least 7percent from REIT compare with mutual fund. I will maintain buying dividend counter and hope I can retire earlier by just having dividend as my pay. The calculation is simple and I plan to have passive income of 3k per month. With 7percent dividend yield, I need (3000x12)/0.07=514285.71 as my initial capital. Wah, half million! Dono when can I gather that amount.
