I need advice can someone help?

How can I make my blank meme (s) less crappy than the ones I see other people made in DeviantArt? Because whenever I try to make my own memes it doesn’t turn out the way I invision it, and when I see somebody else’s blank meme(s) all I see is perfection. I mean, I have a second DA account and I already made a blank meme that I’m satisfied with, but when it comes to making more blank memes again I somehow don’t know how to make it without the boxes being too small or too big and/or running out of space, etc. So, how can I fix my problem?; Is it practice makes perfect? Keep practicing until I get it right? Use a different software? Like, what the heck! If anyone knows I would appreciate it! Thx
