The only thing that constant in life is change.

In terms of changing attitudes and such, yes, it is never too late to change. Although once you're older, you get more set in your ways, thus making it more difficult. But there are also some things that you can't change from the past. Just deal with it and move on. Dwelling on things only makes you less inclined to try new and interesting things.

It is never to late to make a change, but sometimes you need a light push in the right direction too.

Im pretty set in my ways but if things don't improve in life then I have to look in the mirror and see if I am the problem.
