"Look before you leap"

"Those who hesitate are lost"

'just be yourself'

as if you could be someone else.

but this advice is then always followed by 'fake it until you make it' nonsense.

it's basically a way for 'advice givers' to not give advice but feel like they have done so. and then throw up their hands and be a dick when the advice receiver asks for something more specific.

One I encounter at work fairly frequently is "Don't let perfect be the enemy of the good" and "If you don't have time to do it twice, do it right the first time".

The reality is that you need to develop a sense for when you're just spinning your wheels trying to anticipate anything and everything possible, and pit that against the desire to just call something done because it looks like it works in a carefully controlled test situation and you want to move on.

Some things you're only going to catch after letting your idea/plan/program come into contact with reality, but some things are also far better to plan for in advance.

So you just keep adjusting your "ceiling" and "floor" for how far you go when designing shit, and eventually you build a sense for it.

I like the version, "Everything happens for a reason, and sometimes that reason is you're stupid."
