Here's the translation of the text you provided from Hindi to English:
"Even if you are not capable of practice, become devoted to me, and for my sake perform all actions. In performing actions for my sake, you will attain success."
Here, Lord Shri Krishna is explaining that the best path for you is to do everything just as He is doing. If you follow His guidance and perform your actions diligently, you will attain liberation, even if you are not proficient in your tasks.
Lord Krishna is emphasizing that success in life is not just about achieving a particular goal. If you cannot attain a goal or face setbacks in life, you should not think that everything is over. Even during the ups and downs of life, one should strive to live with satisfaction. In this entire world, there is no one who gets everything they desire. What matters is not losing one's precious life in pursuit of things that were not meant to be. Therefore, we should learn to control our desires, find contentment in what we have received, and perform our actions with integrity. We should not grieve over what we did not achieve.
