Owning a Decision

I’ve made the decision to stay home with my children for the next three years and start a daycare. How do I get to place where I own this decision and go all in with being the best Mom I can be and providing the most value to being a Mom as I can. I keep thinking I should do more, or could do more…I know these are just thoughts but I still don’t seem to be able to own that decision to be the best Mom I can be. Thank you!
