Start from today April 6th, I will take a record of the progress of data science learning myself. Before going to bed, all the staff I learned, read, accomplished, thought are supposed to be listed there. On the one hand,  it helps me refresh the data related things I did during the day, keeping them as a record here online. On the other hand, practice writing is always one of my concerns, so it servers as a way to push me writing something each day.

Better thinking, better data understanding, better writing and better English! Although I am still not quite sure if data jobs are fit for me or not, it worth a try and my skill sets currently are quite qualifiable for this field. Sharp my analytical thinking or skills is not a bad thing anyway. Let me insist on it and pursue my dream further.
