Read carefully and remember.

We do three types of Jobs here:
1) Cheap
2) Quick
3) Good

You can have any two, so:

a) A good quick job (won’t be cheap)
b) A cheap good job (won’t be quick)
c) A quick job cheap (won’t be good)

In other words

Cheap + fast = lower quality work
Fast + good = expensive
Good + cheap = not happening anytime soon

There is always a trade off and you should decide what your priorities are.
