Making 3% monthly with covered calls / cash secured puts sounds fesable with solid stocks, right?

What is your opinion on that? I am operating since the 10th of February and have made 1.8% so far with cash secured puts on stocks I want to own. Am I missing something? Can I keep this up? I am not using none of the spreads techniques etc. Also, in my country we have fewer options possibilities and minimum 7DTE which sounds good to me.
