You can't be passionate when you feel like it. You have to be passionate about your job, product or cause all the time. There's no off switch on a tiger.

The truth is, success often occurs for reasons we don't expect, under circumstances over which we have little control and sometimes unrelated to our own efforts.

Don't water your weeds.

Direct your energy toward achieving a goal, and tackle the problems with an emphasis on edging closer to a successful result.
