g young man. it is therefore apparent that thinking is playing a very important role in my life. however, it can be painful at times. although i spend much time thinking, i still cannot sort out some of the problems i encounter. consequently, i will get depressed. it seems that i?m asking for trouble. why not go and have some fun instead of taking pains to think? the reason is that its rewards far outnumber those momentary displeasure. thinking is the key to life, the gateway to psychological maturity, and the beacon to the road ahead. leaning to think is the milestone in my life. it is the most valuable thing i learned at university. now it has bee an indispensable part of my life. amp。 thank you!
