Substantive mit Geschlecht (Nouns with Gender)

One of the biggest frustrations with my German is I never know which gender a noun is. It doesn't help that us English speakers hardly know what gender is in grammar, and that German genders are just a random, hodgepodge of rules. Just kidding, there are no rules to it. But there are some "Almost Rules," in that they can be generally true. When nouns have these endings, they tend to be associated with a certain gender, and knowing this can make life a lot easier. If you can get gender correct at least half the time, I think you are doing pretty good.  (link to Deutsch für Euch video where I learned this)
Male endings: -ig -ich -ling -s
Female endings: -ei -in -heit -keit -ung -schaft -a -ie
Neuter endings: -chen -lein -le -icht -tum -ing -um -ment

Another "Almost Rule" would be that endings with -e are often female, but this is less consistent than the other rules.
