Comfort? I'm not looking for comfort. I accept comfort if it's there and don't notice if it's not. Comfort is a poison and a drug, only addicts run for drugs. The value of the drug is great, but the greater the value, the stronger poison and more need to limit the dose.
The meaning of free will is that a person chooses his own goal (dream) and begins to grow towards it, entering the path of improvement.
