Make the changes you need, and then keep it up.
The first moments are never when things begin. Things started a long time ago when you took that first step to change things, back when no one could see the change you were making, not even you. Back when it seemed like a waste of time, of money, of energy. Back when the problem to solve wasn't even worth solving.
The first moments are often forgotten, if they were even noticed in the first place. When did you become friends? When did your financial problems get better? When did the overtime get smaller? When did the relationship become smoother? When did you end the day less tired?
The first moments are never when things begin. Take the time to make the changes you need, and then keep it up.
