My university life

I am a freshman. I am curious about my future life. I can't be lost in study but i really want to learn new konwledge. I don't know how I can do it. I am always busy with doing meaningless things.This pains me. I am looking for an encouragement to urge me to get improvement   inspire me.

I am not sure what this sentence means - I can't be lost in study but I really want to learn new knowledge.

I think that you can leave out "new knowledge" as learn implies that.

Do you mean by the sentence that I am unsure of ---

I don't want to be behind in my studies as I really want to learn.

I feel that I am lost in study but I really want to learn.

How long is your course ?

In the West, undergraduate courses are typically 3 to 5 years.

The first year is relatively simple as people from various backgrounds are brought up to one standard

and introduced to terminology. Second year is more intense as you start to specialize. Third year is very intense but at that stage, you have decided on one future and really love your chosen field.
