hand 1 is sad face. I used to make these calls before I had a coherent thought process going on in my head. No more, "I'mma do this! *bet get raised* Now I'mma do this!" And you'll be struggling with tilt issues for awhile, probably a huge leak for everyone.

hand 2 is alright but that's really player dependant. Most big bets at low stakes are for value because a lot of people adopt the strategy of trying to out cooler the rest of the table and then get their chips in.
