You can have the right idea and the right plan. You can work harder than your competition. But if you don’t have the right people around you, you won’t succeed.
The people around you should inspire you, challenge you, motivate you, and be there for you when you really need them. You’ll know when you find these people, because you’ll want to run ideas by them, brainstorm with them, and look forward to spending time with them. If, however, the people around you are pulling you down or impeding your progress, you need to seek out other people with whom to surround yourself. It’s that simple.
