Are you trying to achieve big things?
No matter how big or small the changes you’re trying to make, there’s no point in trying to change lots of things at the same time. If you did that it would just cause chaos, and you wouldn’t know what worked and what didn’t.
So instead start by changing one small thing at a time, then another and another. Before you know it you’ll have made a huge different by making significant changes, one small step at a time.
