nobody likes a complainer

The last thing we want to hear is someone complaining, yet we do it all the time. I find myself feeling sorry for myself or feeling like I deserve more. "Med school's hard and taking up my free time" is one of my bigger complains, but honestly, this doesn't serve any purpose except for bringing my colleagues and myself down to a bottomless pit.
Lately in medical school we've been learning about heart murmurs right now and the patient's chief complaint. This led me to think of the time of Moses and their constant "murmuring". In the King James version of the Bible, the common term used for complaining was “murmuring.”
The Lord always considered their complaints as an act of unbelief directed toward Him. When they complained about their circumstances, their type of food, and even at Moses, God was displeased because they weren’t thankful for what He had provided them. He was disappointed that they refused to trust in Him to provide, protect, and direct the order of their lives. A verse here shows God's displeasure with the constant murmuring that often is in our lives. “Now when the people complained, it displeased the LORD; for the LORD heard it, and His anger was aroused. So the fire of the LORD burned among them, and consumed some in the outskirts of the camp” (Numbers 11:1).
Many times, especially lately in medical school when it's been tough, I've found myself murmuring. However, looking at the big picture I feel as silly as the tribe of Israel when they constantly were murmuring to God even though God led them out of slavery, out of Egypt, and giving them the Promised Land. When I look at the big picture, God has given me such a great opportunity to be in the position that I am. He in so many ways has prepared a special path for me, just like how He prepared a special path for the Israelites to the Promised Land.
Being an admirer of John Wooden, the great coach of UCLA, one of his maxims in life (I think he had 5), was to never complain. This I truly something I need to strive for, so from here on out, whoever is reading this, whenever I complain, call me out on it and I'll give you a dollar! Nobody likes a complainer, not even God.
