You are the source of every change you can imagine. If you want to change but don’t want to put in the effort required to make the changes you want to see, nothing will ever change for you.
If you are prepared to work hard to make the changes you want to see, with the passing of time the changes will happen, however, the effort required to maintain the changes you have achieved will not be an effort any more.
The changes you wish to see are possible. You just need to find the right motivation to achieve them.
