Funny, but thats actually one of the ground rules.
First, respect your BR. When you play tournaments or cash games try to bring about 1 to 3 % of your whole bankroll at a table. You can play at higher stakes if you feel confident.
Now about not having the best hand - trust me, you dont have the time to play only when you got the nuts. Poker is a mixed game, even though luck takes a decent place in the game, you cant rely just on that. Or to have the nuts. You need to learn to bluff and stuff, in the right moments, against the right players. Try to play lower SnG's, for example when you lost those 150$, you could have played 1.50 SnG's and not only you wouldnt have lost it that fast, but you would have won a few aswell. But your bankroll was too big for these tournaments to matter. So, if you think you are a decent player, dont play under the influence or something ( alcohol, weed, bad mood ) and read some BRM articles. That usually does the job for you.
