I have some questions about my sentences.
In such situation, taking action now is of more value because it saves the time that are unnecessarily wasted by our overthinkings.
(I'm not sure with the word "overthinking", it seems that this is incorrect, I mean, thinking excessively, is there any better words? )
Buy it now, you get it. Consider for a moment, you miss it
(I just want to express that if you buy it then you can get it, but if you think over for a long time, then you will miss the beautiful cloth. So, can I express my meanings in the way above? )
one must go through a large amount of information and look into every possible details of the consequence of decision
(I use "go through" because I want to emphasize the largeness of the information. but I'm uncertain about it, maybe I made a mistake because I look it up in the dictionary and can not find the meaning I want. )
taking action now would save time for us to plan the future development and make a earlier start.
("plan the future development" seems not very native. is there any suitable expressions? )
