"Helpers" invariably have a desire they are trying to fulfill through the helping.
Most of us have our hands full just working on ourselves. There is very little we can do for others till we have 'helped" ourselves. With that desire foremost there will always be people seeking our help without us looking for them. We just have to recognize when they are ungrateful or we have gotten over our heads and lost our original purpose which is working on ourselves. It is always good to develop that desire. The desire to help and improve ourselves. If we are at all sucessful we will find that others seek us out. Then we have to have the discrimination to know if we can help. Life is continually a learning process.
