Then, you ask...

"What can I do to inspire myself?"

Well, when you were inspired by someone, what was it like?
You were inspired by someone for what that person does, or, the way how that person lives, weren't you?
That means, you can inspire yourself by what you do, or, the way how you live.

Or, if inspiring yourself is not easy, then, how about inspire the closest person/people
Try inspire your spouse by the way how you live.
It is no easy thing, but it is worth it, and it is fun.
