In fact, it is good to have this awareness. If you spend more time blaming yourself, don't say that your third semester 1W3 will be in vain ... your whole experience after dropping out of high school will be in vain! It is better to act than to blame yourself. If you want to do well, do well, save experience and money; If you want to continue studying, you should study your major seriously ... otherwise, you will only live in regret forever.
