Treat the faults or others as gently as you do your own. I really believe that and try to model that every day. Some days I am even successful.
I also believe we are all here to help those around us to be successful, however we can. We are supposed to help each other finds those markers left to guide us on your paths. When we stop looking for them or have forgotten how to see those markers life becomes full of drama, issues and becomes troublesome. Once we get back to seeking them and following the correct path for us the road smooths out.
Life was never meant to become easier the older we get, it just becomes easier to deal with. We should always be working hard and pushing forward to new things.
