If you're playing Mid Garen make sure to skill your shield some time for more resitence(if Mid champ is too strong) always try to open a fight early with your "Q" then "E" and "W" at the last position beacuse of your silence(normal hits of AP Mid Champs aren't very strong right?)

If you're playing Solo Top Garen always try to harrise your enemy early so you can kill them early! If you lost a lot of your life just stay behind your minions some Time and use your Passive to reg. all the life!
