A very common occurrence, but to be honest I don't mind too much, because I have taken the blinds and antes without having to play a hand, sometime's even a minimum raise is enough to take them, sure it is annoying if you think you could have made more from a hand like A/A or K/K, but if played slowly you are always at risk of falling in love with your hand, and losing a lot when they get cracked by a 4/7 hitting a straight, that is another common occurrence.
Raising pre-flop has two advantages, firstly being able to take the blinds without a fight, and also getting the BB to fold
hands they would not normally play, imagine the BB holding 7/2 off and you limp, he checks, then the flop comes 7,7,7, there is no way he is folding, no matter how much you bet, and a flop of any trips gives you a full house so are you folding A/A ?
Be grateful for small victories, even if you could have won bigger pots, you could also lose a bigger pot!
When the fun Stops, STOP!
