I don’t drink coffee and alcohol. I don’t eat candy, chips, cake or anything with excess amounts of sugar and/or fat. I also don’t smoke or do drugs. Neither do I work out.
I just get up early in the morning to learn Russian, then go to school and after that, watch YouTube.
That probably sounds boring, but my future looks good, and my present is also pretty good.
