I am a person with two extremes.Sometimes too confident and sometimes too self-abased.The confidence comes from your strength such as badmation,and more times you are just too self-contempous.It's because you have wasted too much time on something meaningless,and spend little time on what really maters,which makes you don't grasp some necessary skills,such as the ability to type word quickly , writing by word,excel,powerpoint , Pro/E and so on.
Stop waste your precious time!
DO THINGS THAT REALLY MATTERS!
Do what you like and should do when you are still able to do it!
趁年轻,拼起来!
