I'm discussing my journey with KDP.

I began in January of this year and struggled initially, taking three weeks to make my first sale.

In May, I earned $812 in royalties while spending $166 on ads, resulting in a net income of $646.

I've been running a single advertising campaign since February, generating a significant number of impressions, and I've spent a total of $637 on ads over five months, emphasizing the importance of budgeting wisely for business growth.
