Saying to have discipline is easier than actually leading a disciplined life.
I know a lot of people who claim to be disciplined but cannot change their eating habits.
As many times we lie to ourselves.
To be a disciplined person is not easy. Especially if it concerns financial management. To be disciplined takes time and we have to get used to it gradually. Sometimes we have to force ourselves to do it. But if we are used to it, discipline will become easier. Well it was quite difficult at first. But when you get used to it, everything will feel easier.
I used to be a wasteful person. But there was something that pushed me to change my life for the better. Well, I'm also not a person who has good discipline. But I'm trying to become a disciplined person. And sometimes to be disciplined we have to have something that drives us to do it. But in the end we are only human. and we can't be perfect people.
