Be a problem solver, not a problem adder.
One person approaches a situation with the mindset of, “How can I make this work?”
Another type seems to approach each circumstance with the mindset of, “What are all the reasons this wouldn’t work?”
Both people will be forced to deal with reality. Still, the first person will only have to solve problems that occur, while the second person will often avoid taking action entirely because of the potential problems they have dreamt up before starting.
There will always be reasons not to do something.
