Best way to reduce typos?

I hate to proof-read too. Sadly, the best way to get better at typing grammatically-correct sentences (which is what your question is, correct?) is practice & understanding the difference between those words if you aren't sure. Next time you are typing something & notice something you aren't sure of, make a note of it & look it up later (like you're & your). If you know what everything means/what is supposed to be used & it's just a miscommunication between your brain & your fingers, practice & time are the only things that'll fix that. Good luck!
