If you're unwilling to defer pleasure or endure some "pain" for now, are you likely to end up later deep in the hole?

Optimism inspires, energizes, and brings out our best. It points the mind toward possibilities and helps us think creatively past problems.

You carve out the organization's character through your daily choices. You shape its conscience as you exercise your own.

As tough as it sometimes looks on the front end, it's easier to do right than undo wrong.

If you must doubt something, doubt your limits.

Your doubts are not the product of accurate thinking, but habitual thinking. Years ago you excepted flawed conclusions as correct, begin to live your life as if those warped ideas about your potential were true, and ceased the bold experiment in living that brought you many breakthrough behaviors as a child.

No sense being pessimistic. Wouldn't work anyway.
