too fast and lose it

I mean too fast is when making any decision too fast you will lose something you always wanted. It maybe confusing and hard to make a decision at first, whether to choose either this thing or that thing. These two things can give two different things that you wanted. It maybe hard to choose because those two can make you happy and not happy in a different way. So the only way to know which thing give you the best is to look at the bigger picture first before making the decision it may takes time but you will one day know which thing is the best.
