Confusion In Challenges

As today I posted about my traveling adventure when I came back home after a long tour of the northern areas of my country. So now there are a lot of things for me and I’m feeling confused about what should I do?
Actually, I made a “To do list” in the evening and there’re a lot of things. So I need help from all of you. On which task I should focus on?

So here’s the list:
1: My weight is 97kg at this time and I want to lose loss my weight because after one month my classes will start. And this thing needs a lot of hard work and time for exercise, diet and calories count.

2: I want to do an internship in a company so that I’ll experience the atmosphere of the workplace.
3: I’ve bought 3 books to read “A brief history of time” “Lean Startup” “Zero to one”. I want to read these books to increase my knowledge. But there is a lack of time.

4: I want to improve my English speaking and presentation skill for which I want to join a fellowship program.
5: Steemit challenge is also in the list. I want to challenge myself to write a worthy blog on daily basis. It should contain well data and knowledge so I could grow and can benefit others at the same time.

So these are the main list which I want to do. So help me, guys. You can help me in many ways, for example, you could give me one of the above tasks to follow or can also break that in little parts. I really need your help.
