Try and remember what you said you'd do and why you said you'd do it.
Forget what you think other people want the thing you said you'd do to be.
The thing you said you'd do should only be what you want the thing you said you'd do to be.
If the thing you said you'd do makes other people happy, that's great but don't say things or do things just to make them happy.
Find new ways to do the thing you said you'd do that don't change the meaning of what you said you'd do.
Have the purest of intentions for what you said you'd do and do it bravely.
If the thing you said you'd do becomes successful, continue to act and think like it is unsuccessful, otherwise you'll spend your time worrying that it might become unsuccessful.
If you said you'd involve people in the thing you said you'd do, listen to them when they say what they think you should do.
If you said you'd do the thing you said you'd do alone, then go boldly into the wilderness and may your own soul be company enough, while you do the thing you said you'd do.
Do right by the thing you said you'd do. Tend to it and love it.
By trying to remember what you said you'd do and the reason why you said you'd do it.
