Why worry, be happy as the song goes. I've got really, really important roles and goals.  We get ourselves all worked up into a frenzy over our current responsibilities. We are just trying to survive is our excuse for getting ourselves worked up. I believe it's true that stress is the leading cause of all kinds of physical and mental disease. To be healthy; need to be happy, to be happy; you need to not worry.  In Matt 6:25-34 the key to not worrying is seeking first His kingdom. I interpret that as being self focused but God focused. Looking into the purpose that God created us for. Looking around and seeing where I am placing my investments of my resources. Like my time, my work, my relationships. Being at rest, being at peace Is what the world looks for. Letting go a little bit and letting God do in us what He intended for us to do. It's on paper, His word. To change course for the disciples was leaving there nets. For change to take place action is necessary. Invest more in God's kingdom and less in your own, like; prayer, reading the bible, helping your neighbor, being kind to a stranger, giving to someone that isn't expecting it. Open your heart to God's purposes in our world more and the change necessary to be a peace will be yours.  Vs 33b all these things(Love, Joy,& peace) will be given to you as well.
