I am certainly not the first person to say that learning a language can be difficult, based on a lot of factors, but there are is a broad range of perspectives that can hep you on your journey.
Things to Consider:
You have to understand the what/why of your potential learning. Are you learning for fun, or for work? Is it an ancestral language, if not, what draws you to the language you want to learn? Has it always been a passion for you, or do you only want to impress that certain someone in your LING 101 class? This is important because learning a language is an exercise in patience and consistency, in the moments when it's at its most difficult you want to still be able to find what makes it interesting, what brought you to it in the first place.
Now that you have your foundation, if you haven't already, you need to actually pick a language! The options available to you are expansive, at least roughly 6000 languages:
Things to consider:
Do you want something closer to your own language, that allows you to bridge your understanding with less hassle?
Do you want the challenging but oh so satisfying step in to the unknown, venturing far, especially with new alphabets/sounds greatly different from your own?
Start with one language, but sometimes it's nice to change, give yourself a break from your main focus. Light study in a second language can reinforce learning from your primary language if you consider things like similarities/differences. By attempting a deeper understanding of your language you can make subsequent memorization efforts easier.
If you are having difficulties, make sure you aren't too hard on yourself. Have fun, learning these subjects is a great experience, and you never know where it will take you!
