Everything changes. It's inevitable. And usually we don't even realize it before it's too late.
Looking forward, the change is scary. We tend to opt for the current state. The one we know, be it for good or bad. We are afraid things could be worse. And the change, it often requires work. Or at least a decision to be made.
Even if we don't make those decisions, the change still happens. Without asking our permission. The small steps every day take us closer to something new and different. And we might not want to end up there.
That change is also often hard to revert. Once again it had become the norm. We would need to make a decision and work on it to make the change happen. And once again we hesitate. And the change goes on and on.
Once the change has happened, through whatever steps it needed it's usually also irreversible. You can't just take those steps backward and return to the old. The only way is forward.
The change is inevitable. But we have the final say for the direction of that change. As long as we are in control instead of just letting it happen.
