The beginning is half of the whole.

My goal in 2016 is speaking English fluently. I want to be able to speak what's on my mind, so I'll study English and try to speak English with many people. I like the saying, "the beginning is half of the whole". Although it is difficult to achieve this goal, it is worthy by itself. Starting something new always makes me excited. :D

The beginning is half of the whole.

My goal in 2016 is speaking English fluently. At least, I want to(I wish I can) speak what I want to talk freely. So I'll study English and try to speak in English with many people. I like the saying, "The beginning is half of the whole." although it is difficult to achieve the goal, it is worthy by itself(I don't know what you want to mean here). Starting something new always makes me excited. :D

I think the saying should be "The good beginning is a half of the whole", keep it up:)

The beginning is half of the whole.

If you want other ways to write the second sentence you could say:

I want to be able to speak in English freely.

I want to have the opportunity to speak what I want in English easily.

I think your English is good, I hope your studying is going well ^^
