I was always told that crucifying the flesh meant to die to self. Which means anything that you want and even need has to be done away with. In other words if you need money just pray for it and believe God to provide(the bible teaches a man don't work he don't eat)if you need food just pray for it after all God feed Eljiah iwth with the ravens. In other words anything that "normal" people would do is considered fleshly. I have even heard of people saying God told them to leave their jobs and depend entirely upon him. That is not what the bible teaches even Jesus had a job other than preaching. Anything that made you look human was wrong anything that made you look all super spiritual was right. I used to repent for being human. I'm serious I used to cry out to God all the time and say God I can't do this. I can't be like what they say I should be like. I tried so hard. However the more I learned the more I began to realize that these people are not like God that God is not mean that He is not out to get me like they made me feel like,that I didn't have to be perfect. That to stop being human would mean I had to die and it isn't my time yet. We live here on earth in a body made of flesh we live in real situations that need real answers not this stuff that tells us we are wrong for being human and have to repent for being human. The bible says those whom the son has set free is free indeed,it doesn't say that we are free to be in bondage to all these rules.
