إقتباس Classic, your English is really good! However as you have mentioned some of your English sentences are not correct. Try to learn more about grammer just to improve your lovely English. Make sure if you want to use the modal verbs you have to write a main verb after it immediately. For example: you must improve your skills. So we use (improve ) after (must) and we didn't use (to) between them, because it's not a main verb. Hope that is helpful

thank you for your support and also for your advice

thanks a million for all
