Yes, but that change can be hard and not everyone is up to the challenge. Trust me, I'd know. Most people just need motivation and a reason to change. E.G. Realizing that they've been a bad person. Realizing that their attitude is very annoying. But not everyone can change. People such as my father have only changed a little bit since our 3 month "Break" from him. After twelve years of the same ol same ol. We figure it's just impossible to change him for the better. We've tried a million times and it hasn't worked. He wants everything to work his way wether we like it or not, but we have freedom too. Anyway, people like my father just can't change and some can. It's that simple. Most people that can't change have this done due to pride, stubborness, bossiness etc. Point being, not everybody can change, in my opinion most can if they really want, are forced to, etc. But through just twelve years of experience i KNOW for a FACT that some people just won't. Change.
