Treat investing like a business

$AMC Entertainment(AMC.US)$ Im not like those who came in when the price is at 20s. I bought a lot at the 50s so i've lost quit a bit - paper value. My humble opinion is that if you think of this like a business where you need to pay things up front, you will be able to gain the mentality that you can reap the rewards down the road. If all businesses take some losses and decided to call it a day, we wont have our establishments that we see and patronise today.
