Don’t feel bad...we all have this problem...except perhaps the Sisters in a Monastary...and even they have their problems..I don’t think Jesus asked us all to do great things...but to do little things in a great way..you are doing what Jesus wants you to do...work, family, etc.
I feel that I fall short of what I should do also..all we can do is recognize this and pray hard for the Holy Spirit to help us to "do better".
I also think that "more is caught than is taught"...an old saying..but true. Hopefully our good example will also be a means of being a "good Samaratin" to others....God bless!!!
