Everyone is different in terms of comfort and relaxation in placing bets, sometimes it's just like our imagination but what we imagine is comfortable for ourselves, but still control your emotions so as not to do excessive things.
Yeah gambling preferences is one thing that cannot be same with everyone, emotions is one generally big issue most persons has got over time, literally they don't have the strength to completely be in charge only a few persons are actually able to get that done and so they place their bets sometimes not because of they don't have the funds but the emotional imbalance affects them so badly, I literally suffered same sometimes ago, I ended up regretting not having the confidence enough to do what I believed should work for me.
Of course, everyone has a different strategy in betting and even when they have won from the bets they play, some choose to stop and some even lose what they have won from the bets they play, if only they could control their emotions when gambling, of course they would be able to enjoy what they have got, but not everyone can do this when betting and those who can bet casually will of course be able to stop when they have experienced victory and also defeat in the bets they play.
If you have lost your confidence in placing bets, it would be better to take a break from gambling activities first and after you regain your confidence in placing bets, then start betting again. Of course, this would be better than forcing yourself to bet when you lose your confidence in choosing the bets you will place.
