It is hard to succeed at anything that you "hate." You cannot be committed to an endeavor; your heart will just not be in it, if you just don't care. So somehow you are going to need to change your attitude.
You don't mention learning a specific language, so do you just need to learn any language? If that is the case, perhaps you can choose a language that is spoken in a place that interests you. For example, if you are an artist, you would probably appreciate The Louvre and the other great art venues in France, the great french artists, and the places where they painted. So learning French with the idea of learning and understanding more about these places and people, and perhaps with the long term goal of traveling to see them and being able to speak the native language, would motivate you to learn.
As for me, I am learning Spanish because I have long wanted to become bilingual for my own satisfaction, because I love learning and I think it keeps my brain younger and more "fit,"and because I want to return to Cuba next year and be able to speak for myself.
I hope I did not sound too preachy, but you did ask for advice.
