I personally have always loved hills, even know I will never be a "climber". Ride every hill you can find, find a gear that works for you in that hill, probably in your smallest gear in the front, and settle into the best rhythm or cadence you can maintain. Speed is nit the goal, getting to the top is!

When climbing I would always use "goals" when I would feel like I needed to stop..... Just make it to the next mail box, the next guard rail, the next tree. Whatever. Keep from letting yourself get off. If you do need to get off, stop and regain your heart rate and composure, and get back on. I would always try to ride the whole hill or climb even if I needed to stop ( no walking ). Mentally I felt more as I'd I had "made it" and I ways almost always able to go back and do that same hill or climb without stopping when I had the confidence that I could male it up that climb (. Don't doubt the psycological aspect of riding a bike!)
