Yes, it sucks to wait on the higher quality cards. Often, I attempt to play tight, however, I cant do it very well... I would rather be loose at the table than to play tight...
I never won much by playing tight.
It is possible to play as tight as you want, why not? It is possible to play only pocket aces, but by the time you are dealt pocket aces, your stack might be very small due to all the blinds that you kept paying.
