Maybe you are a caculative person. But however strong you are, there is always someone stronger. Maybe you often get what you want with calculative plans. But when you meet these people, your plans and strategies are just a part of their calculations.
1. Monkey
Monkeys are good at hidding their real thinkings. However, they are very clever to observe others. If you try to utilize them, they are keen enough to find this when you just begin. When you proundly think that they are falling in your traps, very probably you are already in the troubles they make for you. Monkeys have very many novel ideas. You never know what they will do next step, and you don't know if the troubles you are meeting are made by them.
2. Snake
Snakes are suscipicous. Once they suspect someone, they start to defend immediately. They are very good planers. When they want to be calculative, they are experts on this. Therefore, if you try to trap a snake, you become probably the victim.
3. Rat
Rats themselves are calculative, although they don't think they are. They are very good at making plans and often execute the plans secrectly. They think that they do so only for controlling the developing processes of the cases they care. Whatever they think about themselves, in the competitions on plotting they are often the winers.
