Be ready if need be to go alone

There's nothing as powerful as teamwork.
There's nothing as leveraging as getting along with others.
But until you are ready to go alone, you cannot be uniquely successful.
When things get tough, allies may renegotiate, but if you were prepared to go alone, you will not be deterred.
Close friends may retreat when the future gets hazy, most people may even tag you lazy; but you only can make them confirm that you are really crazy.
As you pursue your dreams, be ready at some point to go alone.
