To me, if someone wants to quit bad habits he or she should quit one and for all because if the person is try to reduce it slowly it possible he or she will find herself back in that bad habits and even more deep than before.
And quitting is can still make him to see some reasonable point or thing that can still drop him back, so to quit and never back to it.
Though it is hard to quit once and for all but is take self-discipline, so that such person can be free once.
Because it is just like when you said you do not want to engage in harm rubber and you decided to quit slowly, you know one day you might see something that will attract you back to it .
because when you go for an operation that you see a big money and you will see that no you don't need to quit from this, because this is really good, so that is how it is if someone wants to quit from his bad habits need to do it once.
Even I think so. If you have to quit something, you must do it at once. Quitting slowly is like procrastination which might not help as much we want it to. If we try to quit slowly, that means we are still using that thing or habit as a support. But if we quit at once, it might hurt for a day or two but then it's just gone and you are free.
Yes you get me right, we can predict what will happen in the next minute, but is quit and for get about it.
Let is go and go forever, with time you will forget it.
Is not that to quit something (habit) like that once because when the person started that habit slowly ,gradually before he has addicted to that so when he or she want to quit the habit he or needed to quit it slowly because being addicted to something is not easy to quit ones
Just let for go is for go and don't look at it again
Is an elderly world "buy gone is buy gone"
