Having a team is a wonderful thing. When you need encouragement and inspiration, they are there to lend a helping hand. When tasks pile up, there is comfort in knowing the work can be divvied up. With a good team, 99% of the time, assignments get done. (Note here that if your team has a 50/50 chance of delivering, you are carrying dead weight on your project. Good help is reliable. Read Lose Dead Weight for more on that topic.)
Even still, you should depend entirely on no one. If the success of a project is 100% dependent on someone else coming through, you will experience intense amounts of stress and discontentment. Trusting your team to do their part is important. However, the ability to deliver results with or without your team is essential. Depend entirely on no one. Make it so only you stand in the way of your own progress. Empower yourself with whatever is necessary to ensure that you can deliver when others fall off.If someone else has the power to shut you down, somewhere down the line you gave them permission to fondle with your dream.
