You’re going to push your members to their limits for the success of the project. You will become stressed as their performance is unsatisfactory (to your standards). You will feel disappointed. You will point that out to them. They will become unmotivated. They will hate you. Pressure of making the event a success and keeping the team intact is on you. You will sacrifice and at least make them realize that you are already carrying an extra load. They will hate you even more, justifying that “it’s your job”.
And the worst part…
you will not show them any of that weakness because the team and the project will fall apart. You still have to show your strong demeanor and show them that you are still happy.
