When to stop?

You

NEVER

really stop achieving your goal,

because there is always competition, and even when

you don't feel anyone can compete with you;

that's not exactly how they feel.

So whether you achieve the title of

 #1,

the same way

you got it ; the next person is going to get it to.

So the key is the

NEXT STEP

how to keep your name or companies name alive.

Staying involved in the public or the community you strive to be the best in.

 Cause you can never be good at one thing anymore

its always , "well what else can you do".

So learn a new language, do another trade.

Keep pushing to be a better you.
