Common Mistakes:

1) Don’t use will or might directly after will or might. 

If I will arrive first, I’ll make lunch.       => If I arrive first, I’ll make lunch.   

2) Always use an infinitive verb after will and might.

I might to go out tonight, if I’m not too tired.      => I might go out tonight if I’m not too tired.
