Is something that will certainly take place in anyone, anytime, anywhere.
The Buddhist concept of Impermanence, Anicca. All component things are subject to change.
Normally people change for the better. When you see something not right, you know you need to do something about it. But, it doesn't mean that it will always take one change to get to the right side. Paths and journeys are subjective, you might or might not estimate every individual's effect to a certain change.
Taking the big step to change needs a lot of courage and effort, and it differs a lot to individuals. The resultant of the change also differs according to situations. it doesn't mean you try and you will get. How much is your try? "Try to change" and "will change" is miles far apart, that is also why there are two different terms for them!
So much so, I am also in a trial to change now. Mentally, spiritually. It is just how much effort I have put in so far that I am still here now, while someone else could be having a better life from his/her trial and effort. Courage and effort are essential for the before, during and after.
All the best, people.
