By considering this habit as only a playful attitude, you are showing you are aware of it. It is not however a good idea to use style in covering up the impatience. This will play with your own mind. So every day you have to start practicing delaying gratification in other activities to be able to cultivate calmness and to not insist on immediate outcomes to everything you are engaging in in life.
In general, those who take a long-term view have a better chance of success because they're thinking about how to improve themselves today to reap the rewards in the future. I think it's professionals who go through this process; they start training, brainstorming various strategies to improve their game and themselves, to be stronger than others, to prove they're worthy. In any case, those who jump in and play today without improving themselves will play the same way tomorrow, relying solely on luck. Becoming a professional is almost impossible; it's not a long-term perspective.
I don't have a strict strategy to place my bets sometimes I feel like using parleys other time I'll be in the mood for a single game but I really don't mind parkeys I like to compile a few games and wait on them. That patience to wait and see if I get all my predictions right is a thrill for me, although I don't go for very long parleys as some of my bettor friends, just a few games between 3 and max 5.
Parleys helps you to endure which builds your patience and anticipation, we all have little things that gives us entertainment in gambling and this is one of them for me. Betting on single games sometimes puts you under pressure and impatient to see how the game will end but you can do parleys and not bother to watch all the games, you will only be checking for results after each games.
