I have decided to make a serious effort to learn English
You can start your answer in a number of ways;-
I have decided
I have made up my mind
I have made a conscious effort
All these phrases presuppose that you have been too casual in the past.
Then you complete your sentence with
I am going to put all my focus
Make a serious effort
Put all my energy
into learning English
You have now decided that nothing is going to distract you anymore from learning English.
I've decided to study English seriously.
I've decided to focus on my English studies.
Recently, I feel motivated to study English seriously.
Within the first two example sentences, we can use almost the same English structure while using the words, "to study," or, "to focus," with the exception that you use the noun, "studies," along with the verb, "to focus."
Lastly, we can also talk about our motivation with, "I feel motivated," to talk about our recent, growing desire to study more.
I've decided that I want to study English.
I would like to learn English.
You can use any of the above two sentences to tell someone that you would like to learn English, but not for fun.
A; How have you been doing?
B; Good, I have decided I want to study English.
I made up my mind that I will put in a lot of effort to learn English.
When you use the phrase: I made up my mind, that means you have decided on something or you have made the decision to follow through on something. Becoming fluent in English requires a lot of focus and effort.
I am determined to work hard at studying English.
When using the word "determined", like in the sentence above, it emphasizes the fact that you will work hard. This word also means that you will not be easily distracted and that you are willing to work hard to become fluent in English.
I decided to buckle down and learn English
If you 'buckle down' it means that you start a task with determination. Of course, your mind may wander and other things may interrupt your progress. However, if you are buckling down then you are ignoring these distractions and getting on with the job in hand!
"John is really buckling down to his homework now!"
I've decided to work hard to learn English.
I'm going to take English lessons more often.
I want to improve my English, so I'm going to work harder.
To work hard at something means that you are going to put a lot of time and effort into it. You are going to spend more time that you currently do to learn English or you are going to work harder in the time that you are already using to learn English.
To improve means to get better at something.
Example: I am going to improve my listening skills by listening to the radio for an hour each day.
I am going to study English seriously.
I am going to take my studies with English seriously.
I am going to get serious with my English studies.
Good luck with it all, I hope it goes well, and I hope you greatly improve yourself.
How is your English going?
Try one out, see how it goes, and see which one suits you.
I hope this helps.
Have a great day.
I made a resolution to study English.
I am dedicated to learning English.
I decide to give my all, in learning English.
In the sentences above, you are conveying the idea that you are serious about learning the English language. For some reason, you have gained the motivation needed to achieve your goal. This may be the case for work, travel or a hobby that you have decided to take up.
In the first sentence, the word 'resolution' means making a firm decision to do something. You will not be swayed, or you won't quickly change your mind with regards to this.
To be dedicated means to give all your effort into something. When you put a lot of effort into something, you're not likely to give up easily.
'To give one's all' means to put in a lot of effort, time and maybe even resources into achieving something.
Therefore, these sentences are appropriate in conveying the meaning stated in the outset.
I decided to study English seriously.
I really wanted to improve my English, so I started studying seriously.
To describe when you had a change of mindset and doing something much more in order to learn it, you can use the description 'seriously' (adj). This means that you are taking the subject 'seriously' instead of just doing it for fun.
