Everyone has a peak at doing something before it goes downhill. It could be quite straightforward like how a sportsperson’s body can no longer keep up the same pace. Or it could be because you just aren’t quite as up to date and responsive like you used to be.
To try and reduce negative impact, you need to acknowledge that you are winning. It might be due to real hard work or talent. Or it could also be due to luck. Whatever it is that got you where you are will not last forever. You might be lucky if you have someone you can fairly compare with to see how you are faring. This is the easiest gauge there is.
Nobody likes to quit when they are winning, and this is not really the point of this post. It is best to stop or leave while you are still up there though. This keeps you in good spirits to go for the next adventure. It also makes sure you leave others with a good impression, as that could be fuel for other things.
In any case, we should celebrate our victories however big or small. This gives us the strength to face days that are not as great.
