The more effort, the more lucky

Note: I am a native English speaker, but I am not a grammar whiz. I am happy to help you with your English, but I will respond with what I think would be the most natural way to express what you are saying.  

The more you try, the luckier you will be.

Lately, two thoughts have entered my mind. The first relates to an English learner who has complained on Italki about not being able to find a partner to help with his essays, while English speakers have little difficulty finding partners to learn their target language. The second is my experience with finding a native English speaker to speak with on Skype, which I had looked forward to for a long time. In fact, when the line was connected, I realized that I didn't even know how to start a conversation. I almost couldn't say a complete sentence, I was so nervous and excited. After hanging up, I found that sweat was dripping from my forehead.

What I want to say is that while a partner is helpful, getting yourself ready to begin speaking is even more important. If you have no solid language base, speaking with a native speaker will frustrate you more than it will help you.

Note: I congratulate you on trying to speak to a native English speaker even though you are nervous! Your written English is quite easy to understand. I am trying to learn French and I feel the same way, though I haven't found the confidence to try speaking the language yet. I do think that trying to speak your target language with another person is a key element of learning the language, and hope you continue to try. I would be happy to speak with you once I sort out how to do this online.

English is such a common language that many people want to learn to speak it - so there is likely a lot of demand to find a partner to speak English with. Personally, I would like to speak French with someone, however I have very little knowledge or experience with other languages - so I have not yet looked for a partner to exchange languages skills with.

The more effort, the more lucky

That guy said that he could not find a /had no /language partner to practice his English with, and nobody had ever helped him to correct  his essays , while the English native speakers who wanted to learn a language of their choice got more help and interest from others .lot of reaction when they wanted to learn their target language.
The second is luckily for me to have an opportunity to talked to an English native speaker on skype.> The second is about the conversation I had with an English native speaker, an opportunity that I was lucky enough to have.

I had looked forward to that for a long time. Previously, I thought I had learned enough vocabulary for basic a simple conversation/ communication. In fact, But, to be honest, when I the line was connected, I even didn't even know how to start a simple one/conversation.

I nearly couldn't say a complete sentence during the later conversation.I was nervous and excit. After hanging up, I found that sweat dripped from my forehead. > I could not string a complete sentence most of the time during the later part of our conversation. I was too nervous and excited. After we hung up, I found sweat dripping down my forehead.

What I want to say is : A partner is helpful, but getting ready by oneself is more important. If you have no solid basis, talking to a native speaker will not help you but frustrating you hard!

> What I want to say is this: To have a language partner is helpful, but, more importantly, we must prepare ourselves first so that we are ready for any one-to-one conversation. If you do not have a good foundation in the language, talking to a native speaker will not be of much help-- and it may even get you feeling more frustrated.

Always put a space after a comma or a period.

What I want to say is :  XX > The introductory phrase before a colon must be complete, independent and standalone . It must not be "hanging". >  I just want to say this:   > complete> ok . What I want to say is : > incomplete XX
