Today i was busy with the beginning in MySQL , i have the feeling that, i spent a lot of time to read it, see video , but in generally , it is just uneffective .

My mind was fixed , it is very bad for a junior Programmer , why i muss continuosly learning the new thing . What i have learnt in some day of this week is just remind what i have learnt before and enxpand it a little bit more .

MySQL is the one of the most popular workbech for Programmer to get Database , it is old and complicated for me.

Tomorow , i will not go to CodeGym, i am spending 1 day, alone , to just concentrate in this section . I hope everything will get better .
