Planned action leads generally to a positive consequense

This is not always true. Planned action such as a premeditated murder has a negative consequence. While, on the other hand, a planned action such as doing your homework first thing when you get home, can have a positive consequence such as having more free time to do what you wish.

Most of the time planned actions do lead to positive consequences. the reason why is if you are planing out what is going to happen you will know ahead how it could effect something or someone.
