Supporting another person's success is an exceptional strategy to support your own.
Because when you do...
You are sending a message to the universe that you love winning.
This is exactly what will help support the efforts you're putting in to create your own wins.
At the same time...
The opposite is true when you hate on somebody else's success.
You are telling the universe that you hate winning and do not want any for yourself.
Winners win...
...and help each other win too.
Losers lose...
...and hate on everyone they see winning.
