Sudhama ji and all other people from Vrindavan had seen lord and all his leelas. They were present there physically and seen everything that the lord did. It is very natural for them to feel the true love for the lord. However people like us have only read about the lord and his pastimes in scriptures. We only have the information via books and I guess none of us have ever seen the lord except a very few people. So how can we get the same level of love for the lord from inside? I know it will be really difficult for all of us because most of us have neither experienced the lord nor seen him. But we can try to the best of our abilities. How can we generate the true love feeling for the lord from inside us as I believe lord has given us everything and everything is already present inside us but we just need to realise it! If once we feel the love for the lord from inside us, then for sure lord will notice us and everything in life will be taken care of. How can one truly love the lord without any selfish motive of ours? Most of the people worship lord with some motive in their minds. How can we stop worshipping like that? If we don't have any selfish motive only then we can love the lord completely.
