An exercise guaranteed to make you less effective is to compare yourself with others.
There's always someone else seeing more patients, making more money and playing with more expensive toys than you. And by the way, the reverse is also true. Regardless of your situation there's always someone else in more dire straits who would gladly trade places with you.
Comparing yourself with others is a sign of ungratefulness. Envying what others appear to have is being unappreciative for what you've been given. It's one of the ugly facets of pride that blocks further blessings. It keeps us small, petty and ineffective.
Instead, be genuinely thankful. If you have a challenge, be grateful. If you have troubles, be appreciative. If you have a void you need filled, remain cheerful. It's an opportunity to prove your worthiness for greater responsibility, greater service and further blessings. Only when you honor what you have do you prove that you can be entrusted with more.
