Hi Serafina. I read the article and agree with Ynaig. It is like saying, I cant be as happy as you because I have a low tolerance to joy. The "tolerance" comes from what you focus more on - good thoughts lead to more good thoughts which lead to joy and more joy. Feeling unworthy is based on resistant beliefs, a feeling of not being good enough. These are wrong beliefs because we are all worthy of having whatever we desire as a birthright. Negative beliefs mean negative thoughts mean negative feelings mean less joy.
