So I want to start a new modded Youtube series. I have the mods Lucky Block, Blue Lucky Block, and Optifine. However, for some reason, when I use Forge 1.8, it won't load. I don't even get an error message. Minecraft just doesn't load...help?

We can't really do anything without some logs.
If you have no crash reports, go to your mc launcher, hit Edit Profile, select keep launcher open. Hit save profile. Then start your MC, and when it fails to load, go back to launcher and copy paste here contents of tabs called launcher log and game output.

This is an error technically called: "User not paying attention to what he's doing."

I thought 1.8 and 1.8.1 were compatible?

No. People try to force the two together for reasons unknown and end up with issues. There is optifine for 1.8.0 for a reason.
