Positive thinking does not mean you have to find every idea absolutely wonderful. It does mean you have to be ready to explore idea and to try and bring out whatever good features it has. The next step might be to find the (weak) in the idea and to try and strengthen them, rather than use them (simple) as an excuse for rejecting the whole idea. Finally, after the idea has been explored, it may not (use), because there is a (good) one or because, it is good but not (suit). There is nothing wrong with being positive about an idea at first and then rejecting it (late), when you see that it won't work.
is easy to be negative and critical and too much talent is wasted in negative thinking. It is time that we (show) less respect for this kind of destructive thinking and focused positive thinking more. So remember to think positively.
