Practice makes perfect

I think practice makes perfect.Whatever you do.（这第一句是啥意思？）（可以改成Whatever you do,I think practice makes perfect makes sense .（自己回去搜make sense））When I was a child,I learned to play the violin.I liked it very much.So I tried my best to learn and practice it every day.As a result,I could play the violin well.I was very happy.
When I had my first job,I could't doing anything(用know nothing about it比较好。你的本意是什么都不会做？).But I worked hard.I practiced drawing and playing the piano.If I had some questions ,I asked my colleagues for help.They were very helpful.
Now I learn English every day.I read English and recite words very hard.I often write some compositions.My English is better than before.After all ,I am trying my best.I do  believe that practice makes perfect.(do在这里是强调语气，我确实相信XXX。这里用believe in不太适合，不能做信仰的，还不如就用从句了。)

Practice makes perfect

I think practice makes perfect. Whatever you do. When I was a child, I learned the violin. I liked it very much, so I tried my best to learn it and practice every day. As a result, I could play the violin well. I was very happy.
When I had my first job, I couldn't doing anything. But I worked hard. I practiced drawing and playing. If I had some questions, I asked my colleague for help. They were very helpful.
Now I learn English every day. I read English and try to remember words very well. I often write some compositions. My English is better than before. After all, I am trying my best. I believe that practice makes perfect.
