Motivate comes from motive which means to cause to move or having the power to move something.
Inspire comes from Latin which means to breathe, and means to breathe into, to infuse into something through breath or to infuse into the mind.
With the challenges which face people every day in growing up, choosing careers, succeeding in the workplace, raising families etc., I think that inspiration is a good thing to get a dose of every once in a while.
It is not a sign of weakness to seek-out more wisdom about the process of living and life. It is in fact a sign of strength and intelligence because although we are certainly born with all the potentiality to be great, no one handed you a manual when you were born, which explained life and how to go about succeeding at it. That process is left up to the individual to find out through the trials and errors of living; so sharing wisdom in this regard can help reduce the slippery slopes and increase the successes.
I think Einstein said it best:
“Learn from yesterday, live for today, hope for tomorrow. The important thing is not to stop questioning.”
