Patience

Patience?  Patience is tough sometimes.  When we get caught up with all our daily responsibilities and challenges, being patient can be difficult.  Patience is a virtue.  It is developed from either good genetics or learned from those we have interacted with the most.
Being patient can be very beneficial to our health both psychological and physical.
Bottom line is we either are a patient person or else we must commit to developing patience if we want to be healthier.  (especially parents)
This is not to say when something needs to be addressed we should tolerate or sit by and idly hope for it to change.  NO.  Just when you can not do anything to change the situation at the moment and must accept it or some aspect of it or just for now then be patient.  Use the time to figure out what needs to change or what you can do so you are not challenges again. 
Patience takes practice. lots of practice if it doesn't come naturally.  Bottom line is our feelings come from our thoughts.  What are you thinking when you are lacking patience?  Change your thoughts and your feelings will change too.
If you cant figure this out on your own or need a little assistance seek professional help.  This is an easier fix than you think.
For parents, remember they are the children.  Try not to use up all your patience on one child, your spouse, or at work...hahaha you will need a reserve at all times.  deep breath the challenge is right around the corner. 
It is not what others do but how we react to them that might help change future behavior. 

It is indeed a wonderful virtue to possess and so beneficial to develop the skill of patience!
