>To create a good project we need (an) effective plan. There are few points
>why planning is so important.(I'll try to) explain some of them. The
>first point is, that if we have good plan we can (save) lots of time
>during creating a project. Saving time leads us to lower cost. (With)
>planning we can stick to (the) points and our project is more reliable
>and detailed. (Furthermore), planning is important(,) because we can see
>all the aspects of our project and (even) find alternative
>solution for some points in (it). Additionally, if we have plan
>we can stay calm(,) because we know what is the next step in our project.
>Moreover, if we describe our project (then) we can compare it to our
>plan (and) see if we did everything as we planned. It is irreplaceable
>because it helps us (to) estimate results of our work. In my opinion,
>planning is important not only in creating a project(,) but generally in
>our life. If we want to achieve a success(,) we should make plans.
