The BEST chess advice would be __________________

the internet is filled with advice. therefore the best advice I got was to stick to one book at a time. don't try to learn 20 things at the same time.

before that advice I was reading 10 books and learning something from each book and at the same time watching 25 chess videos.

The BEST chess advice would be make good moves.

Position the board so that the sun is in the opponents eyes

The Best chess advice would be make the best moves

LOL 

Now that goes against the rules. You're supposed to apportion the sun before you begin....

Quit now and do something useful.

Not possible.  The Sun is way too big. 

Play players that are stronger than you, you can learn quite a bit just from your own games.

 I have to ask what do you define as a good move.

sometimes I get the urge to "set the board on fire" with a more or less dubious move. even if it is dubius I have a plan sometimes I win by it.

some play 1.e4 2.c5 .Na3?! even GM's but they have a plan.

A good move is a move that either maintains or improves your chances of winning the game.
