do not give up

I always tell myself "do not give up". I read an essay about sports, it shows me how to make a sport to a habit. Therefore , I want to make running a for my habit. I am running almost one hour three times one a week. However, the running doesn't become a my habit. I am tired and it is hard to continue. I told myself "do not give up" , maybe tomorrow things will be changed. Do not give up!
English is also hard to learn for me, I take a long time to study English. It looks like it never imporves (changed to good). Sometimes , I am sad and worry. I also told myself do not give up, maybe tomorrow I will better.

We do not give up easily. Things are hard to begin and get bettergo on. However, we trust ourselves, we are stronger than we can imagine
