I was chatting with Woebot and he taught me something so great that I decided I would share.

So let's start.

You are twisted between two decisions and you don't know how to? You decide to be smart and put maths in the action.

Let's choose a random decision. Windows 10 vs Linux! Because, why not?

The decision to wipe a system and put either Win 10 or Linux. Let's start the calculation!

A will be the Win 10 option.

B will be the Linux option.

Each option has a pro and con:

A will have I and II.

B will have III and IV.

We start with A.

Set the advantage of A:

I. An improved computer.

Set the disadvantage of A:

II. Loss of previous data.

Now set the relevancy of the pro and con so that they sum up to 100:

I. 65

II. 35

Now B.

Set the advantage of B:

III. A new OS.

IV. Learning Linux 101.

Now set the relevancy of the pro and con so that they sum up to 100:

III. 55

IV. 45

We set the advantage comparison of both A and B:

a. 55

b. 45

We set the disadvantage comparison of both A and B:

c. 45

d. 55

We can now proceed to the real stuff!

Calculated decision.

We calculate the advantages of A:

The formula is ( I + a )

NB: a is the advantage of option A

W: ( 65 + 55) =120

We calculate the disadvantages for A:

The formula is ( II + c)

NB: c is the disadvantage of option A

X: ( 35 + 45 ) = 80

We calculate the total for option A:

Total(A) = ( W - X )

Total(A) = 120 - 80

Total(A) = 40

The result can be positive or negative, it is OK.

We calculate the advantages of B:

The formula is ( III + b )

NB: b is the advantage of option B

Y: ( 55 + 45) = 100

We calculate the disadvantages of B:

The formula is ( IV + d)

NB: d is the disadvantage of option A

Z: ( 45 + 55 ) = 100

We calculate the total for option B:

Total(B) = ( Y - Z )

Total(B) = 100 - 100

Total(B) = 0

The result can be positive or negative, it is OK.

Final Assessment!

We compare Total(A) and Total(B):

Here we have 40 > 0

Result: Clear decision! This means I should go for option A.

Note:

If Total(A) = Total(B), result is a "Can't lose" decision. You choose either.

If Total(A) < 0 and Total(B) < 0, result is a "No win". This means you are definitely not convinced at all.

I am going to do it again because B feels more appealing to me than A but A is easier.
