When nothing is sure, everything is possible.
Sentiment: POSITIVE
The only certainty is that nothing is certain.
My personal philosophy is, you can be sure of nothing.
When we are not sure, we are alive.
In these matters the only certainty is that nothing is certain.
One thing is sure. We have to do something. We have to do the best we know how at the moment... If it doesn't turn out right, we can modify it as we go along.
It is certain because it is impossible.
Everything is theoretically impossible, until it is done.
Doubt begins only at the last frontiers of what is possible.
Nothing is impossible. Some things are just less likely than others.
There is no such uncertainty as a sure thing.
