I have tried this too and it really works. Whenever you face any problem where you have to decide a solution or choose a decision between two things, try this theory. Flip a coin with one of the option on head and others on tail. Toss the coin and you will get the answer. The moment that coin will be in the air, your heart will be expecting a head or tail. That expectation of head or tail is your solution. You don't even need to see the result that either it is a head or tail. If you try to solve the problem the problem by making pros and cons list. You are gonna get the same wieghtage on both side. Try this and get to know what your heart says.
