People these days give up so easily. They usually end up finishing what they started just because they don't believe it's worth it.
But when you love someone, when you truly love someone you will never give up. Even if you feel like something it's not working, you'll have to think about what to do to make it work. Don't hide it to yourself, try to share it with the other person. Fight for what's making you happy 24/7, don't just give up and finish it. Work on it. If it's worth it, what didn't work once, it will work later and that "problem" will just make your love stronger.
Don't just stop talking to the other person so that your feelings will go away. Don't try to tell yourself you're not good enough, because it that person is with you it's because you're more than good for that someone. Don't convince yourself there's no way of fixing that problem, there is always a solution, no matter what the problem is. Don't blame your feelings for existing, blame yourself for trying to forget them as soon as possible.
There is pain in love. There are tears in love. But what really makes it worth it is if both of you fight for the other's happiness. If you smile just by reading a message, by knowing the other person is thinking about you, by listening to someone's voice, by remembering old memories... That is happiness. If you see that the other person it's not as happy as you are, you'll do anything to change that. If someone's pain becomes your pain, if someone's tears become your sadness or angriness... That's it. It's love. You both feel the same, no matter where you are, who you are with or why you feel like that.
So don't you ever give up on what really makes you the happiest person in the world.
"Let it be. Don't make the same mistakes as me, cause I gave up quickly."
