If the only way you can move ahead is by pulling other people down it just plain is not worth it.
If the only quiver you have in your arsenal is to insult or hurt then maybe you should do something else.
It seems to be the popular way now a days to get ahead ( or at least that is what people think )- pull others down around you so you rise.
The major problem with this is it creates a false bottom and a weak foundation. Even if it works in the short run it will catch up to you.
The best way to move ahead is WITH others NOT in spite of them.
Build a coalition - knock down the walls- find common ground.
Do YOUR job- and help those around you along the way and you will succeed and build a solid foundation and one that will feel good and last for years.
