@homeyji Most of us in US  are more than average in study (based on personal assumption might be wrong). We expect a lot when we come here but when it comes to reality, it takes awfully long just to graduate. When we see our friends graduate in Nepal, we feel left behind. We tend to compare ourselves with others, we don't see what we got rather stress ourselves with questions as what if I had done that or what if that didn't happen. I am pretty sure that each one of us have a lot of things that other people back home or even here envy on and viceversa. We got to work hard but at the same time we have to take a break to see what we have achieved and what we can do to make it better. Most of us have a very big aim, to work in a big company, own a nice car, and have a faithful wife. I am not saying we can't get it but its too big of a dream to start with. It creates a lot of burden and causes us to stress. To motivate myself, i don't demotivate myself at first. I don't compare other's success with mine rather I celebrate other's success and get back to my own business. I see one class at a time and a semester at most ( its different to plan higher classes). I talk to my close ones on what i achieved ( it makes u feel a lot better). Simply, i see, hear and process what i want.  When i see a glass of water, i focus on water than the other empty half. 
Just my two cents.
