Make it an effort not to focus on the little things that cause us to get so upset and frazzled. Make it an effort to focus on God. When we focus on Him we are trusting in His grand plan for our life. Pray for your faith to be increased and daily trust in Him for all things.
Finally, brothers and sisters, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things. Phillipians 4:8
