There's times to be impulsive and follow your gut feeling. Sometimes I saw technicals that were clearly telling me to not buy, but I trust my gut feeling, sixth sense, or whatever, impulsively made a big bet and I won a lot of money. So sometimes it pays off, but you can fuck up real bad, so be aware of that.
Sometimes impulsive playing works well than planned,though we really need a planned game to determine if were really winning or were losing too much , but if you have a lot of coins and not needing it for certain there's no need to plan just follow your luck ,if its with you while playing.
