Receiving the Gifts of Limits

I've been slowly reading and taking notes on a chapter called "Receive the gift of Limits" this week in a book I'm currently reading.  It has been challenging for me and has I have journaled through the chapter I have thought about the verse in 1 Corinthians that says "Only let each person lead the life that the Lord has assigned to him and to which God has called him".  I very much have a mentality a lot of times of "I want to help everybody, I want to do everything, etc"  The thing is even Jesus had limits and He has given us limits.  I can't do everything and I can't save the world.  I'm constantly thinking about what I should be involved in, what else I can do to help people in NYC, who I want to spend time with, etc.   BUT the Lord is really showing me how terribly wrong my motives are much of the time.  As I was honest with myself and with the Lord I realize how deceptive my heart is and how sometimes what comes across good is actually really really sinful.  I want to control things in my life, how I spend my time, and who I spend my time with.  It's not that I don't seek the Lord in decisions in my life, because I definitely do, but I know deep down there is still so much sin in how I make decisions regarding my time and people.  I bring this up because I've been thinking about it a lot lately.  I was recently challenged by a conversation with a friend where I noticed how purposefully she lives her life.  Every decision she makes regarding her time and relationships has great purpose in it.  I know that we don't need to analyze every hour of the day, but I do want to live with purpose.  I want to focus on certain relationship that are going to be honoring to the Lord and realize that I can't be everybody's friend.  I want to to focus on a specific area to serve, but know that I can't serve in every organization or help every homeless person I see on the street. And I can't feel guilty about it.  I want to be confident in the job that the Lord has me in today and realize that I am making a difference in my job instead of constantly thinking about all the jobs I'm not doing that maybe I should be doing.  Most importantly I want to let go of the sin that so easily entangles me with my time and decisions of how I spend it.  I will always have limits in my life and I can't live like I don't.  God has made me a certain way and has called me to a certain life and I want to live fully in the life He has called me.  I'm not sure I know how to do this well, but I want to ask the Lord to help me fight in this area of my life.  I want to talk to people who are older than me and have more life experience to know how they make decisions about their time.  Some of it is continuing to learn myself, my giftings, my weaknesses, what I enjoy.  I know that my life will never be in perfect order, but I want to flourish as the person God has made me in the place in life He has me.
