I planted some seeds — and from next day onwards I had to check on them because they were mine

I even shared this example many times which is that when I moved into this house there was small garden outside which already had some plant centuries. So one day I planted some, so I put some seeds in the ground just to see how they come up. And I noticed that next day onwards first I would want to check on those because those were mine. So what is it that made them mine? What is it that makes things mine? My relationship, my security, my money, my master, my freedom, my ideas.
