Getting your money in with best hand is great, try getting your money in with the best hand after the river, I hear that works too. It would also be advantageous to have more chips than your opponents.

Honestly dude, bad beats happen a ton and they always will. If you play good poker you generally will get sucked out on way more than you will do it to other ppl. That is just the way it works. What sucks about poker is you can play perfectly relative to your competition and lose, there are not many other sports like that. In fact, I cannot think of anything like it.
