Several others have said it but yeah...get up on the front of the seat to get some weight forward, get your arms tucked in to your body and low. This will put you over the front of the bike and keep some weight on your front wheel to keep it on the ground. Don't worry about trying to hammer up the hill in some insane gear, drop it all the way to the bottom if that's what it takes and then just keep your seat and pedal.

Guess what? You're going to suck for some time like the rest of us did. You're going to end up doing the hike-a-bike just like the rest of us did. But, if you keep with it you'll build muscle and skill and before long you'll be taking on climbs and finding them easier and easier.

Good luck.
