Believe my thought…time to choose a new one??

My thought for this month was “I can reach one hundred pounds”. It’s taken a long time and a lot of bridge thoughts there but I’ve got it! The feeling of doubt sometimes kicks in but I still know it’s true for me. Is it time to decide on a new thought? If so, should I move onto a different topic (i.e. my coaching business) or keep it related to weight? I’d love some specific thought suggestions. Thank you!
