1. I do not recommend you watch 奋斗 and learn grammar!!!! But you should watch it to practice your listening and speaking.
Because 奋斗 is a very easy-going tv series, it is funny, but do not believe the grammar, it will take you to the wrong direction. I am born in beijing and live in beijing until I move to Sweden, trust me, when beijingness speak, we do not care so much about the grammar! >.< Try watch some Documentary film e.g. A Bite of China(舌尖上的中国), it not only can help you with grammar, words... but also give you know more knowledge about Chinese culture.
2. I suggest you that learning Chinese start by expend your vocabulary, do not focus on grammar tooooo much! yes, it is important, but you will see as long as you have enough words, practice, grammar will be just there, to become to your friend. So practice as much as possible the words that you learned everyday.
You can do it! You are also welcome to learn Chinese with me!
Hope you will like my suggestions.
