Anything can be changed, so what?
Look at this red brick. He has become half of the original thickness. It’s change slowly from day to day. Friction with the floor has made the stone growing thin. If we have a look just in 1 and 2 days there was no clearly visible changes has happened, but check it out after a few months, a few years is has become so thin.
In this life we also find the same lessons to learn, both in terms of positive and negative things.
In the negative case, think and careful about this. What a people has heard and what he has seen would give him an influence. How much? As much as his willingness to accept. We will be like what we hear, will will be like what we read, and would like what we see. Be careful, small changes, if allowed to continue influencing us, it will produce big changes.
