The same also applies in gambling when you with take your time to do analyze and enter the market with such analysis for you to find out that the market goes against your order which finally bring your losses. This same is what many gamblers are experiencing and it's normal and no one should see it as something that it's a big mistake and will make you not to do your research and analyze the bet you want to gamble for. We keep making financial decisions Everyday which is a good reason why we need to know what we are doing and focus on what is giving us money as a gambler.
Researching about what brings money to our pockets as gamblers also include researching what kind of gambling best fits our interest. Sometimes it is good to try out something new in gambling, a new game entirely or a new strategy of analyzing your gambling games. Sticking yourself to one form of gambling for so long might not be profitable, I am not saying that you have to switch over your gambles consistently. No. When a strategy works for you, work with it for a while before modifying it or changing entirely. Be open to adjustments and evolving.
Overanalyzing games to me isn't a bad practice to me. What might be bad to me instead is not being confident in your own judgements or analysis. When you don't gamble with some level of confidence, you will end up gambling with confusion there by canceling games to win into failure.
