As others have said, down shift early. I have found on my 14 mile loop (there are 4 inclines) that if I down shift to first gear I can pedal up them without stopping. I could not do this a week ago but did figure it out. I also don't look at the top of the incline but pick a point part way up and tell myself I can take a break when I get then. Once I am there (usually an intersection) I ride to the right (the flat of the intersection) then keep going. I have been riding about 2 months now and it does get easier.
