Optimistic 5 Nov 2018
Optimism appears to be a French invention. Voltaire in 1750 wrote in French language about optimism, a kind of belief that the good will ultimately prevail.
Therefore optimism a relatively modern word.
Does it work?
Optimism does not help with doing things that you are not prepared for.
It may help with uncertain tasks where you need to persevere.
Interesting is that optimism certainly is not a guarantee for success.
Is it healthy?
It is healthy to have a good confidence that I can do my normal tasks and that I can learn and enjoy a few new things.
